I am not sure whether what I found here amounts to a bug, I might be
doing something dumb.
During the last few months I did tests by running pgbench over logical
replication. Earlier emails have details.
The basic form of that now works well (and the fix has been comitted)
but as I looked over my testing program I noticed one change I made to
it, already many weeks ago:
In the cleanup during startup (pre-flight check you might say) and also
before the end, instead of
echo "delete from pg_subscription;" | psql -qXp $port2 -- (1)
I changed that (as I say, many weeks ago) to:
echo "delete from pg_subscription;
delete from pg_subscription_rel;
delete from pg_replication_origin; " | psql -qXp $port2 -- (2)
This occurs (2x) inside the bash function clean_pubsub(), in main test
script pgbench_detail2.sh
This change was an effort to ensure to arrive at a 'clean' start (and
end-) state which would always be the same.
All my more recent testing (and that of Mark, I have to assume) was thus
done with (2).
Now, looking at the script again I am thinking that it would be
reasonable to expect that after issuing
delete from pg_subscription;
the other 2 tables are /also/ cleaned, automatically, as a consequence.
(Is this reasonable? this is really the main question of this email).
So I removed the latter two delete statements again, and ran the tests
again with the form in (1)
I have established that (after a number of successful cycles) the test
stops succeeding with in the replica log repetitions of:
2017-06-07 22:10:29.057 CEST [2421] LOG: logical replication apply
worker for subscription "sub1" has started
2017-06-07 22:10:29.057 CEST [2421] ERROR: could not find free
replication state slot for replication origin with OID 11
2017-06-07 22:10:29.057 CEST [2421] HINT: Increase
max_replication_slots and try again.
2017-06-07 22:10:29.058 CEST [2061] LOG: worker process: logical
replication worker for subscription 29235 (PID 2421) exited with exit
code 1
when I manually 'clean up' by doing:
delete from pg_replication_origin;
then, and only then, does the session finish and succeed ('replica ok').
So to me it looks as if there is an omission of
pg_replication_origin-cleanup when pg_description is deleted.
Does that make sense? All this is probably vague and I am only posting
in the hope that Petr (or someone else) perhaps immediately understands
what goes wrong, with even his limited amount of info.
In the meantime I will try to dig up more detailed info...
thanks,
Erik Rijkers

I don't think it's reasonable to expect that the system recovers
automatically from what amounts to catalog corruption. You should be
using the DDL that removes subscriptions instead.

You're right, that makes sense.
Thanks.

Hmm, they are not cleaned automatically, deleting from system catalogs
manually like this never propagates to related tables, we don't use FKs
there.

Yeah because you consumed all the origins (I am still not huge fan of
how that limit works, but that's separate discussion).

There is no omission, origin is not supposed to be deleted automatically
unless you use DROP SUBSCRIPTION.

Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and perhaps more things later.

* [PATCH v28 2/5] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and maybe more.

* [PATCH v25 2/5] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and perhaps more things later.

* [PATCH v28 2/5] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and maybe more.

* [PATCH v24 2/5] Add pg_depend.refobjversion.

on collation versions for indexes and perhaps more things later.

* [PATCH v24 2/5] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and perhaps more things later.

* [PATCH v27 2/5] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and maybe more.

* [PATCH v24 2/5] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and perhaps more things later.

* [PATCH v25 2/5] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and perhaps more things later.

* [PATCH v28 2/5] Add pg_depend.refobjversion.
@ 2019-05-28 18:16 Thomas Munro <[email protected]>

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and maybe more.

* [PATCH v24 2/5] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and perhaps more things later.

* [PATCH v28 2/5] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and maybe more.

* [PATCH v29 3/6] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and maybe more.

* [PATCH v27 2/5] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and maybe more.

* [PATCH v20 2/5] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and perhaps more things later.

* [PATCH v24 2/5] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and perhaps more things later.

* [PATCH v16 2/7] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and perhaps more things later.

* [PATCH v28 2/5] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and maybe more.

* [PATCH v28 2/5] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and maybe more.

on collation versions for indexes and maybe more.

* [PATCH v24 2/5] Add pg_depend.refobjversion.

From: Thomas Munro @ 2019-05-28 18:16 UTC (permalink / raw)
Provide a place for the version of referenced database objects to be
recorded. Later commits will be able to use this to record dependencies
on collation versions for indexes and perhaps more things later.

* [PATCH v25 2/5] Add pg_depend.refobjversion.

on collation versions for indexes and perhaps more things later.

I think if we limit it to "does plus add comments or not" is a bit too
narrow a definition. Maybe "BACKSLASH_CMD_OPTS" that takes a
comma-separated list, say
\pset BACKSLASH_CMD_OPTS comments,expanded
and with that then all commands behave as if the '*' and 'x' options had
been given.
