Hi Sawada san,
I just had a quick look to 0001 and 0002 patch here is the few suggestions.
patch: v27-0001:
Typo: s/non-temprary/non-temporary
----
patch: v27-0002: (Note:The left-hand number is the line number in the
v27-0002 patch):

This prolog style is not consistent with the other function in the file.
And here are the few typos:

+Atomic Commit for Distributed Transactions
+===========================================
+
+The atomic commit feature enables us to commit and rollback either all of
+foreign servers or nothing. This ensures that the database data is always left
+in a consistent state in term of federated database.
+
+
+Commit Sequence of Global Transactions
+---------------------------------------
+
+We employee two-phase commit protocol to achieve commit among all foreign
+servers atomically. The sequence of distributed transaction commit consists
+of the following four steps:
+
+1. Foreign Server Registration
+During executor node initialization, accessed foreign servers are registered
+to the list FdwXactAtomicCommitParticipants, which is maintained by
+PostgreSQL's the global transaction manager (GTM), as a distributed transaction
+participant. The registered foreign transactions are tracked until the end of
+transaction.
+
+2. Pre-Commit phase (1st phase of two-phase commit)
+we record the corresponding WAL indicating that the foreign server is involved
+with the current transaction before doing PREPARE all foreign transactions.
+Thus in case we loose connectivity to the foreign server or crash ourselves,
+we will remember that we might have prepared transaction on the foreign
+server, and try to resolve it when connectivity is restored or after crash
+recovery.
+
+The two-phase commit is required only if the transaction modified two or more
+servers including the local node. In other case, we can commit them at this
+step by calling CommitForeignTransaction() API and no need further operation.
+
+After that we prepare all foreign transactions by calling
+PrepareForeignTransaction() API. If we failed on any of them we change to
+rollback, therefore at this time some participants might be prepared whereas
+some are not prepared. The former foreign transactions need to be resolved
+using pg_resolve_foreign_xact() manually and the latter ends transaction
+in one-phase by calling RollbackForeignTransaction() API.
+
+3. Commit locally
+Once we've prepared all of them, commit the transaction locally.
+
+4. Post-Commit Phase (2nd phase of two-phase commit)
+The steps so far are done by the backend process committing the transaction but
+this resolution step (commit or rollback) is done by the foreign transaction
+resolver process. The backend process inserts itself to the wait queue, and
+then wake up the resolver process (or request to launch new one if necessary).
+The resolver process enqueue the waiter and fetch the distributed transaction
+information that the backend is waiting for. Once all foreign transaction are
+committed or rollbacked the resolver process wake up the waiter.
+
+
+Foreign Data Wrapper Callbacks for Transaction Management
+-----------------------------------------------------------
+
+The core GTM manages the status of individual foreign transactions and calls
+transaction management callback functions according to its status. Each
+callback functions PrepareForeignTransaction, CommitForeignTransaction and
+RollbackForeignTransaction is responsible for either PREPARE, COMMIT or
+ROLLBACK the transaction on the foreign server respectively.
+FdwXactRslvState->flags could contain FDWXACT_FLAG_ONEPHASE, meaning FDW can
+commit or rollback the foreign transaction in one-phase. On failure during
+processing a foreign transaction, FDW needs to raise an error. However, FDW
+must accept ERRCODE_UNDEFINED_OBJECT error during committing or rolling back a
+foreign transaction, because there is a race condition that the coordinator
+could crash in time between the resolution is completed and writing the WAL
+removing the FdwXact entry.
+
+
+Foreign Transactions Status
+----------------------------
+
+Every foreign transactions has an FdwXact entry. When preparing a foreign
+transaction a FdwXact entry of which status starts from FDWXACT_STATUS_INITIAL
+are created with WAL logging. The status changes to FDWXACT_STATUS_PREPARED
+after the foreign transaction is prepared and it changes to
+FDWXACT_STATUS_PREPARING, FDWXACT_STATUS_COMMITTING and FDWXACT_STATUS_ABORTING
+before the foreign transaction is prepared, committed and aborted by FDW
+callback functions respectively(*1). And the status then changes to
+FDWXACT_STATUS_RESOLVED once the foreign transaction are resolved, and then
+the corresponding FdwXact entry is removed with WAL logging. If failed during
+processing foreign transaction (e.g., preparing, committing or aborting) the
+status changes back to the previous status. Therefore the status
+FDWXACT_STATUS_xxxING appear only during the foreign transaction is being
+processed by an FDW callback function.
+
+FdwXact entries recovered during the recovery are marked as in-doubt if the
+corresponding local transaction is not prepared transaction. The initial
+status is FDWXACT_STATUS_PREPARED(*2). Because the foreign transaction was
+being processed we cannot know the exact status. So we regard it as PREPARED
+for safety.
+
+The foreign transaction status transition is illustrated by the following graph
+describing the FdwXact->status:

+ *
+ * fdwxact.c
+ * PostgreSQL global transaction manager for foreign servers.
+ *
+ * To achieve commit among all foreign servers atomically, we employee
+ * two-phase commit protocol, which is a type of atomic commitment
+ * protocol(ACP). The basic strategy is that we prepare all of the remote
+ * transactions before committing locally and commit them after committing
+ * locally.
+ *
+ * During executor node initialization, they can register the foreign server
+ * by calling either RegisterFdwXactByRelId() or RegisterFdwXactByServerId()
+ * to participate it to a group for global commit. The foreign servers are
+ * registered if FDW has both CommitForeignTransaction API and
+ * RollbackForeignTransaction API. Registered participant servers are identified
+ * by OIDs of foreign server and user.
+ *
+ * During pre-commit of local transaction, we prepare the transaction on
+ * foreign server everywhere. And after committing or rolling back locally,
+ * we notify the resolver process and tell it to commit or rollback those
+ * transactions. If we ask it to commit, we also tell it to notify us when
+ * it's done, so that we can wait interruptibly for it to finish, and so
+ * that we're not trying to locally do work that might fail after foreign
+ * transaction are committed.
+ *
+ * The best performing way to manage the waiting backends is to have a
+ * queue of waiting backends, so that we can avoid searching the through all
+ * foreign transactions each time we receive a request. We have one queue
+ * of which elements are ordered by the timestamp that they expect to be
+ * processed at. Before waiting for foreign transactions being resolved the
+ * backend enqueues with the timestamp that they expects to be processed.
+ * Similarly if failed to resolve them, it enqueues again with new timestamp
+ * (its timestamp + foreign_xact_resolution_interval).
+ *
+ * If any network failure, server crash occurs or user stopped waiting
+ * prepared foreign transactions are left in in-doubt state (aka. in-doubt
+ * transaction). Foreign transactions in in-doubt state are not resolved
+ * automatically so must be processed manually using by
+ * pg_resovle_foreign_xact() function.
+ *
+ * Two-phase commit protocol is required if the transaction modified two or
+ * more servers including itself. In other case, all foreign transactions are
+ * committed or rolled back during pre-commit.
+ *
+ * LOCKING
+ *
+ * Whenever a foreign transaction is processed by FDW, the corresponding
+ * FdwXact entry is update. In order to protect the entry from concurrent
+ * removing we need to hold a lock on the entry or a lock for entire global
+ * array. However, we don't want to hold the lock during FDW is processing the
+ * foreign transaction that may take a unpredictable time. To avoid this, the
+ * in-memory data of foreign transaction follows a locking model based on
+ * four linked concepts:
+ *
+ * * A foreign transaction's status variable is switched using the LWLock
+ * FdwXactLock, which need to be hold in exclusive mode when updating the
+ * status, while readers need to hold it in shared mode when looking at the
+ * status.
+ * * A process who is going to update FdwXact entry cannot process foreign
+ * transaction that is being resolved.
+ * * So setting the status to FDWXACT_STATUS_PREPARING,
+ * FDWXACT_STATUS_COMMITTING or FDWXACT_STATUS_ABORTING, which makes foreign
+ * transaction in-progress states, means to own the FdwXact entry, which
+ * protect it from updating/removing by concurrent writers.
+ * * Individual fields are protected by mutex where only the backend owning
+ * the foreign transaction is authorized to update the fields from its own
+ * one.
+ *
+ * Therefore, before doing PREPARE, COMMIT PREPARED or ROLLBACK PREPARED a
+ * process who is going to call transaction callback functions needs to change
+ * the status to the corresponding status above while holding FdwXactLock in
+ * exclusive mode, and call callback function after releasing the lock.
+ *
+ * RECOVERY
+ *
+ * During replay WAL and replication FdwXactCtl also holds information about
+ * active prepared foreign transaction that haven't been moved to disk yet.
+ *
+ * Replay of fdwxact records happens by the following rules:
+ *
+ * * At the beginning of recovery, pg_fdwxacts is scanned once, filling FdwXact
+ * with entries marked with fdwxact->inredo and fdwxact->ondisk. FdwXact file
+ * data older than the XID horizon of the redo position are discarded.
+ * * On PREPARE redo, the foreign transaction is added to FdwXactCtl->fdwxacts.
+ * We set fdwxact->inredo to true for such entries.
+ * * On Checkpoint we iterate through FdwXactCtl->fdwxacts entries that
+ * have fdwxact->inredo set and are behind the redo_horizon. We save
+ * them to disk and then set fdwxact->ondisk to true.
+ * * On resolution we delete the entry from FdwXactCtl->fdwxacts. If
+ * fdwxact->ondisk is true, the corresponding entry from the disk is
+ * additionally deleted.
+ * * RecoverFdwXacts() and PrescanFdwXacts() have been modified to go through
+ * fdwxact->inredo entries that have not made it to disk.
+ *
+ * These replay rules are borrowed from twophase.c

Hi Sawada San,
I have been further reviewing and testing the transaction involving
multiple server patches.
Overall the patches are working as expected bar a few important exceptions.
So as discussed over the call I have fixed the issues I found during the
testing
and also rebased the patches with the current head of the master branch.
So can you please have a look at the attached updated patches.
Below is the list of changes I have made on top of V18 patches.
1- In register_fdwxact(), As we are just storing the callback function
pointers from
FdwRoutine in fdw_part structure, So I think we can avoid calling
GetFdwRoutineByServerId() in TopMemoryContext.
So I have moved the MemoryContextSwitch to TopMemoryContext after the
GetFdwRoutineByServerId() call.
2- If PrepareForeignTransaction functionality is not present in some FDW
then
during the registration process we should only set the
XACT_FLAGS_FDWNOPREPARE
transaction flag if the modified flag is also set for that server. As for
the server that has
not done any data modification within the transaction we do not do
two-phase commit anyway.
3- I have moved the foreign_twophase_commit in sample file after
max_foreign_transaction_resolvers because the default value of
max_foreign_transaction_resolvers
is 0 and enabling the foreign_twophase_commit produces an error with default
configuration parameter positioning in postgresql.conf
Also, foreign_twophase_commit configuration was missing the comments
about allowed values in the sample config file.
4- Setting ForeignTwophaseCommitIsRequired in
is_foreign_twophase_commit_required()
function does not seem to be the correct place. The reason being, even when
*is_foreign_twophase_commit_required() *returns true after setting
ForeignTwophaseCommitIsRequired
to true, we could still end up not using the two-phase commit in the case
when some server does
not support two-phase commit and foreign_twophase_commit is set to
FOREIGN_TWOPHASE_COMMIT_PREFER
mode. So I have moved the ForeignTwophaseCommitIsRequired assignment to
PreCommit_FdwXacts()
function after doing the prepare transaction.
6- In prefer mode, we commit the transaction in single-phase if the server
does not support
the two-phase commit. But instead of doing the single-phase commit right
away,
IMHO the better way is to wait until all the two-phase transactions are
successfully prepared
on servers that support the two-phase. Since an error during a "PREPARE"
stage would
rollback the transaction and in that case, we would end up with committed
transactions on
the server that lacks the support of the two-phase commit.
So I have modified the flow a little bit and instead of doing a one-phase
commit right away
the servers that do not support a two-phase commit is added to another list
and that list is
processed after once we have successfully prepared all the transactions on
two-phase supported
foreign servers. Although this technique is also not bulletproof, still it
is better than doing
the one-phase commits before doing the PREPAREs.
Also, I think we can improve on this one by throwing an error even in PREFER
mode if there is more than one server that had data modified within the
transaction
and lacks the two-phase commit support.
7- Added a pfree() and list_free_deep() in PreCommit_FdwXacts() to reclaim
the
memory if fdw_part is removed from the list
8- The function FdwXactWaitToBeResolved() was bailing out as soon as it
finds
(FdwXactParticipants == NIL). The problem with that was in the case of
"COMMIT/ROLLBACK PREPARED" we always get FdwXactParticipants = NIL and
effectively the foreign prepared transactions(if any) associated with
locally
prepared transactions were never getting resolved automatically.
postgres=# BEGIN;
BEGIN
INSERT INTO test_local VALUES ( 2, 'TWO');
INSERT 0 1
INSERT INTO test_foreign_s1 VALUES ( 2, 'TWO');
INSERT 0 1
INSERT INTO test_foreign_s2 VALUES ( 2, 'TWO');
INSERT 0 1
postgres=*# PREPARE TRANSACTION 'local_prepared';
PREPARE TRANSACTION
postgres=# select * from pg_foreign_xacts ;
dbid | xid | serverid | userid | status | in_doubt | identifier
-------+-----+----------+--------+----------+----------+----------------------------
12929 | 515 | 16389 | 10 | prepared | f |
fx_1339567411_515_16389_10
12929 | 515 | 16391 | 10 | prepared | f |
fx_1963224020_515_16391_10
(2 rows)
-- Now commit the prepared transaction
postgres=# COMMIT PREPARED 'local_prepared';
COMMIT PREPARED
--Foreign prepared transactions associated with 'local_prepared' not
resolved
postgres=#
postgres=# select * from pg_foreign_xacts ;
dbid | xid | serverid | userid | status | in_doubt | identifier
-------+-----+----------+--------+----------+----------+----------------------------
12929 | 515 | 16389 | 10 | prepared | f |
fx_1339567411_515_16389_10
12929 | 515 | 16391 | 10 | prepared | f |
fx_1963224020_515_16391_10
(2 rows)
So to fix this in case of the two-phase transaction, the function checks
the existence
of associated foreign prepared transactions before bailing out.
9- In function XlogReadFdwXactData() XLogBeginRead call was missing before
XLogReadRecord()
that was causing the crash during recovery.
10- incorporated set_ps_display() signature change.

+Atomic Commit for Distributed Transactions
+===========================================
+
+The atomic commit feature enables us to commit and rollback either all of
+foreign servers or nothing. This ensures that the database data is always left
+in a consistent state in term of federated database.
+
+
+Commit Sequence of Global Transactions
+---------------------------------------
+
+We employee two-phase commit protocol to achieve commit among all foreign
+servers atomically. The sequence of distributed transaction commit consists
+of the following four steps:
+
+1. Foreign Server Registration
+During executor node initialization, accessed foreign servers are registered
+to the list FdwXactAtomicCommitParticipants, which is maintained by
+PostgreSQL's the global transaction manager (GTM), as a distributed transaction
+participant. The registered foreign transactions are tracked until the end of
+transaction.
+
+2. Pre-Commit phase (1st phase of two-phase commit)
+we record the corresponding WAL indicating that the foreign server is involved
+with the current transaction before doing PREPARE all foreign transactions.
+Thus in case we loose connectivity to the foreign server or crash ourselves,
+we will remember that we might have prepared transaction on the foreign
+server, and try to resolve it when connectivity is restored or after crash
+recovery.
+
+The two-phase commit is required only if the transaction modified two or more
+servers including the local node. In other case, we can commit them at this
+step by calling CommitForeignTransaction() API and no need further operation.
+
+After that we prepare all foreign transactions by calling
+PrepareForeignTransaction() API. If we failed on any of them we change to
+rollback, therefore at this time some participants might be prepared whereas
+some are not prepared. The former foreign transactions need to be resolved
+using pg_resolve_foreign_xact() manually and the latter ends transaction
+in one-phase by calling RollbackForeignTransaction() API.
+
+3. Commit locally
+Once we've prepared all of them, commit the transaction locally.
+
+4. Post-Commit Phase (2nd phase of two-phase commit)
+The steps so far are done by the backend process committing the transaction but
+this resolution step (commit or rollback) is done by the foreign transaction
+resolver process. The backend process inserts itself to the wait queue, and
+then wake up the resolver process (or request to launch new one if necessary).
+The resolver process enqueue the waiter and fetch the distributed transaction
+information that the backend is waiting for. Once all foreign transaction are
+committed or rollbacked the resolver process wake up the waiter.
+
+
+Foreign Data Wrapper Callbacks for Transaction Management
+-----------------------------------------------------------
+
+The core GTM manages the status of individual foreign transactions and calls
+transaction management callback functions according to its status. Each
+callback functions PrepareForeignTransaction, CommitForeignTransaction and
+RollbackForeignTransaction is responsible for either PREPARE, COMMIT or
+ROLLBACK the transaction on the foreign server respectively.
+FdwXactRslvState->flags could contain FDWXACT_FLAG_ONEPHASE, meaning FDW can
+commit or rollback the foreign transaction in one-phase. On failure during
+processing a foreign transaction, FDW needs to raise an error. However, FDW
+must accept ERRCODE_UNDEFINED_OBJECT error during committing or rolling back a
+foreign transaction, because there is a race condition that the coordinator
+could crash in time between the resolution is completed and writing the WAL
+removing the FdwXact entry.
+
+
+Foreign Transactions Status
+----------------------------
+
+Every foreign transactions has an FdwXact entry. When preparing a foreign
+transaction a FdwXact entry of which status starts from FDWXACT_STATUS_INITIAL
+are created with WAL logging. The status changes to FDWXACT_STATUS_PREPARED
+after the foreign transaction is prepared and it changes to
+FDWXACT_STATUS_PREPARING, FDWXACT_STATUS_COMMITTING and FDWXACT_STATUS_ABORTING
+before the foreign transaction is prepared, committed and aborted by FDW
+callback functions respectively(*1). And the status then changes to
+FDWXACT_STATUS_RESOLVED once the foreign transaction are resolved, and then
+the corresponding FdwXact entry is removed with WAL logging. If failed during
+processing foreign transaction (e.g., preparing, committing or aborting) the
+status changes back to the previous status. Therefore the status
+FDWXACT_STATUS_xxxING appear only during the foreign transaction is being
+processed by an FDW callback function.
+
+FdwXact entries recovered during the recovery are marked as in-doubt if the
+corresponding local transaction is not prepared transaction. The initial
+status is FDWXACT_STATUS_PREPARED(*2). Because the foreign transaction was
+being processed we cannot know the exact status. So we regard it as PREPARED
+for safety.
+
+The foreign transaction status transition is illustrated by the following graph
+describing the FdwXact->status:
+
+ +----------------------------------------------------+
+ | INVALID |
+ +----------------------------------------------------+
+ | | |
+ | v |
+ | +---------------------+ |
+ | | INITIAL | |

+ *
+ * fdwxact.c
+ * PostgreSQL global transaction manager for foreign servers.
+ *
+ * To achieve commit among all foreign servers atomically, we employee
+ * two-phase commit protocol, which is a type of atomic commitment
+ * protocol(ACP). The basic strategy is that we prepare all of the remote
+ * transactions before committing locally and commit them after committing
+ * locally.
+ *
+ * During executor node initialization, they can register the foreign server
+ * by calling either RegisterFdwXactByRelId() or RegisterFdwXactByServerId()
+ * to participate it to a group for global commit. The foreign servers are
+ * registered if FDW has both CommitForeignTransaction API and
+ * RollbackForeignTransaction API. Registered participant servers are identified
+ * by OIDs of foreign server and user.
+ *
+ * During pre-commit of local transaction, we prepare the transaction on
+ * foreign server everywhere. And after committing or rolling back locally,
+ * we notify the resolver process and tell it to commit or rollback those
+ * transactions. If we ask it to commit, we also tell it to notify us when
+ * it's done, so that we can wait interruptibly for it to finish, and so
+ * that we're not trying to locally do work that might fail after foreign
+ * transaction are committed.
+ *
+ * The best performing way to manage the waiting backends is to have a
+ * queue of waiting backends, so that we can avoid searching the through all
+ * foreign transactions each time we receive a request. We have one queue
+ * of which elements are ordered by the timestamp that they expect to be
+ * processed at. Before waiting for foreign transactions being resolved the
+ * backend enqueues with the timestamp that they expects to be processed.
+ * Similarly if failed to resolve them, it enqueues again with new timestamp
+ * (its timestamp + foreign_xact_resolution_interval).
+ *
+ * If any network failure, server crash occurs or user stopped waiting
+ * prepared foreign transactions are left in in-doubt state (aka. in-doubt
+ * transaction). Foreign transactions in in-doubt state are not resolved
+ * automatically so must be processed manually using by
+ * pg_resovle_foreign_xact() function.
+ *
+ * Two-phase commit protocol is required if the transaction modified two or
+ * more servers including itself. In other case, all foreign transactions are
+ * committed or rolled back during pre-commit.
+ *
+ * LOCKING
+ *
+ * Whenever a foreign transaction is processed by FDW, the corresponding
+ * FdwXact entry is update. In order to protect the entry from concurrent
+ * removing we need to hold a lock on the entry or a lock for entire global
+ * array. However, we don't want to hold the lock during FDW is processing the
+ * foreign transaction that may take a unpredictable time. To avoid this, the
+ * in-memory data of foreign transaction follows a locking model based on
+ * four linked concepts:
+ *
+ * * A foreign transaction's status variable is switched using the LWLock
+ * FdwXactLock, which need to be hold in exclusive mode when updating the
+ * status, while readers need to hold it in shared mode when looking at the
+ * status.
+ * * A process who is going to update FdwXact entry cannot process foreign
+ * transaction that is being resolved.
+ * * So setting the status to FDWXACT_STATUS_PREPARING,
+ * FDWXACT_STATUS_COMMITTING or FDWXACT_STATUS_ABORTING, which makes foreign
+ * transaction in-progress states, means to own the FdwXact entry, which
+ * protect it from updating/removing by concurrent writers.
+ * * Individual fields are protected by mutex where only the backend owning
+ * the foreign transaction is authorized to update the fields from its own
+ * one.
+ *
+ * Therefore, before doing PREPARE, COMMIT PREPARED or ROLLBACK PREPARED a
+ * process who is going to call transaction callback functions needs to change
+ * the status to the corresponding status above while holding FdwXactLock in
+ * exclusive mode, and call callback function after releasing the lock.
+ *
+ * RECOVERY
+ *
+ * During replay WAL and replication FdwXactCtl also holds information about
+ * active prepared foreign transaction that haven't been moved to disk yet.
+ *
+ * Replay of fdwxact records happens by the following rules:
+ *
+ * * At the beginning of recovery, pg_fdwxacts is scanned once, filling FdwXact
+ * with entries marked with fdwxact->inredo and fdwxact->ondisk. FdwXact file
+ * data older than the XID horizon of the redo position are discarded.
+ * * On PREPARE redo, the foreign transaction is added to FdwXactCtl->fdwxacts.
+ * We set fdwxact->inredo to true for such entries.
+ * * On Checkpoint we iterate through FdwXactCtl->fdwxacts entries that
+ * have fdwxact->inredo set and are behind the redo_horizon. We save
+ * them to disk and then set fdwxact->ondisk to true.
+ * * On resolution we delete the entry from FdwXactCtl->fdwxacts. If
+ * fdwxact->ondisk is true, the corresponding entry from the disk is
+ * additionally deleted.
+ * * RecoverFdwXacts() and PrescanFdwXacts() have been modified to go through
+ * fdwxact->inredo entries that have not made it to disk.
+ *
+ * These replay rules are borrowed from twophase.c

When an error occurred before the local commit, a 2pc-unsupported
server could be rolled back or committed depending on the error
timing. On the other hand all 2pc-supported servers are always rolled
back when an error occurred before the local commit. Therefore even if
we change the order of COMMIT and PREPARE it is still possible that we
will end up committing the part of 2pc-unsupported servers while
rolling back others including 2pc-supported servers.
I guess the motivation of your change is that since errors are likely
to happen during executing PREPARE on foreign servers, we can minimize
the possibility of rolling back 2pc-unsupported servers by deferring
the commit of 2pc-unsupported server as much as possible. Is that
right?

Hmm the current logic seems complex. Maybe we can just reverse the
order of COMMIT and PREPARE; do PREPARE on all 2pc-supported and
modified servers first and then do COMMIT on others?

IIUC the concept of PREFER mode is that the transaction uses 2pc only
for 2pc-supported servers. IOW, even if the transaction modifies on a
2pc-unsupported server we can proceed with the commit if in PREFER
mode, which cannot if in REQUIRED mode. What is the motivation of your
above idea?

I think at the end of the transaction we free entries of
FdwXactParticipants list and set FdwXactParticipants to NIL. Why do we
need to do that in PreCommit_FdwXacts()?

Good catch. But looking at your change, we should not accept the case
where FdwXactParticipants == NULL but TwoPhaseExists(wait_xid) ==
false.
if (FdwXactParticipants == NIL)
{
/*
* If we are here because of COMMIT/ROLLBACK PREPARED then the
* FdwXactParticipants list would be empty. So we need to
* see if there are any foreign prepared transactions exists
* for this prepared transaction
*/
if (TwoPhaseExists(wait_xid))
{
List *foreign_trans = NIL;
foreign_trans = get_fdwxacts(MyDatabaseId,
wait_xid, InvalidOid, InvalidOid,
false, false, true);
if (foreign_trans == NIL)
return;
list_free(foreign_trans);
}
}

Thanks.
Regarding other changes you did in v19 patch, I have some comments:
1.
+ ereport(LOG,
+ (errmsg("trying to %s the foreign transaction
associated with transaction %u on server %u",
+ fdwxact->status ==
FDWXACT_STATUS_COMMITTING?"COMMIT":"ABORT",
+ fdwxact->local_xid,
fdwxact->serverid)));
+
Why do we need to emit LOG message in pg_resolve_foreign_xact() SQL function?

We need to move the entry of FdwXactResolution to right before
Hash/Batch/Allocating for alphabetical order.
I've incorporated your changes I agreed with to my local branch and
will incorporate other changes after discussion. I'll also do more
test and self-review and will submit the latest version patch.

Yes, that is correct. The idea of doing the COMMIT on NON-2pc-supported
servers
after all the PREPAREs are successful is to minimize the chances of partial
commits.
And as you mentioned there will still be chances of getting a partial
commit even with
this approach but the probability of that would be less than what it is
with the
current sequence.

I was thinking that we could change the behavior of PREFER mode such that
we only allow
to COMMIT the transaction if the transaction needs to do a single-phase
commit on one
server only. That way we can ensure that we would never end up with partial
commit.
One Idea in this regards would be to switch the local transaction to commit
using 2pc
if there is a total of only one foreign server that does not support the
2pc in the transaction,
ensuring that 1-pc commit servers should always be less than or equal to 1.
and if there are more
than one foreign server requires 1-pc then we just throw an error.
However having said that, I am not 100% sure if its a good or an acceptable
Idea, and
I am okay with continuing with the current behavior of PREFER mode if we
put it in the
document that this mode can cause a partial commit.

Correct me if I am wrong, The fdw_part structures are created in
TopMemoryContext
and if that fdw_part structure is removed from the list at pre_commit stage
(because we did 1-PC COMMIT on it) then it would leak memory.

Sorry my bad, its a mistake on my part. we should just return from the
function when
FdwXactParticipants == NULL but TwoPhaseExists(wait_xid) == false.
if (TwoPhaseExists(wait_xid))
{
List *foreign_trans = NIL;
foreign_trans = get_fdwxacts(MyDatabaseId, wait_xid,
InvalidOid, InvalidOid,
false, false, true);
if (foreign_trans == NIL)
return;
list_free(foreign_trans);
}

That change was not intended to get into the patch file. I had done it
during testing to
quickly get info on which way the transaction is going to be resolved.

Meanwhile, I found a couple of more small issues, One is the break
statement missing
i n pgstat_get_wait_ipc() and secondly fdwxact_relaunch_resolvers()
could return un-initialized value.
I am attaching a small patch for these changes that can be applied on top
of existing
patches.

I think it's good to avoid a partial commit by using your idea but if
we want to avoid a partial commit we can use the 'required' mode,
which requires all participant servers to support 2pc. We throw an
error if participant servers include even one 2pc-unsupported server
is modified within the transaction. Of course if the participant node
is only one 2pc-unsupported server it can use 1pc even in the
'required' mode.

I might be missing your point but I suppose this idea is to do
something like the following?
1. prepare the local transaction
2. commit the foreign transaction on 2pc-unsupported server
3. commit the prepared local transaction

There will three types of servers: (a) a server doesn't support any
transaction API, (b) a server supports only commit and rollback API
and (c) a server supports all APIs (commit, rollback and prepare).
Currently postgres transaction manager manages only server-(b) and
server-(c), adds them to FdwXactParticipants. I'm considering changing
the code so that it adds also server-(a) to FdwXactParticipants, in
order to track the number of server-(a) involved in the transaction.
But it doesn't insert FdwXact entry for it, and manage transactions on
these servers.
The reason is this; if we want to have the 'required' mode strictly
require all participant servers to support 2pc, we should use 2pc when
(# of server-(a) + # of server-(b) + # of server-(c)) >= 2. But since
currently we just track the modification on a server-(a) by a flag we
cannot handle the case where two server-(a) are modified in the
transaction. On the other hand, if we don't consider server-(a) the
transaction could end up with a partial commit when a server-(a)
participates in the transaction. Therefore I'm thinking of the above
change so that the transaction manager can ensure that a partial
commit doesn't happen in the 'required' mode. What do you think?

The fdw_part structures are created in TopTransactionContext so these
are freed at the end of the transaction.

Thank you for the patch!
I'm updating the patches because current behavior in error case would
not be good. For example, when an error occurs in the prepare phase,
prepared transactions are left as in-doubt transaction. And these
transactions are not handled by the resolver process. That means that
a user could need to resolve these transactions manually every abort
time, which is not good. In abort case, I think that prepared
transactions can be resolved by the backend itself, rather than
leaving them for the resolver. I'll submit the updated patch.
Regards,

* [PATCH v45 2/8] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44b 2/4] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v45 2/8] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v45 2/8] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.

* [PATCH 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.

* [PATCH v44b 2/4] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v45 2/8] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44b 2/4] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44b 2/4] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v45 2/8] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v45 2/8] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v45 2/8] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44b 2/4] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44b 2/4] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v45 2/8] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v45 2/8] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44b 2/4] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v45 2/8] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44b 2/4] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44b 2/4] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the

* [PATCH 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44b 2/4] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44b 2/4] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the

* [PATCH v45 2/8] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44b 2/4] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v45 2/8] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.

* [PATCH v44b 2/4] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44b 2/4] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44b 2/4] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v45 2/8] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v43 2/7] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v44 02/10] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

* [PATCH v45 2/8] Do not dereference varattrib_4b in VARSIZE_4B.

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).

Since VARSIZE_ANY() may call VARSIZE_4B(), it's possible that the compiler
(when invoked with -Warray-bounds) complains if the argument of VARSIZE_ANY()
is actually smaller than what VARSIZE_4B() expects. This patch adjusts the
VARSIZE_4B() macro so that it does not have to dereference the varattrib_4b
structure. We assume that varlena value always starts with the length word.
The problem does not exist in the tree at the moment since the current users
of VARSIZE_ANY() pass a pointer to a dynamically allocated memory, so the
compiler has no idea about the memory available. However, in an upcoming
patch, it makes sense to pass a pointer to a local variable of "varlena"
type. In such a case, the compiler warning might appear because
sizeof(varlena) is lower than sizeof(varattrib_4b).
