Thanks.

It would be desirable, for sure.  I've not noticed anything remarkably
unportable in the code, so probably it's just a matter of getting the
build infrastructure to build it.  I suppose that we aren't going to
update the src/tools/msvc scripts anymore, so getting meson to handle
it should be enough??

It wasn't that big; I posted it in the thread discussing that change.

I think the real issue might just be that, assuming we bump the
pg_bsd_indent version number, that in itself would force interested
committers to update their copy Right Now.  I'd rather give a little
notice.

* An incorrect check in get_memoize_path
@ 2025-04-07 07:50 Richard Guo <[email protected]>
  2025-04-08 06:32 ` Re: An incorrect check in get_memoize_path Richard Guo <[email protected]>

  0 siblings, 2 replies; 25+ messages in thread

From: Richard Guo @ 2025-04-07 07:50 UTC (permalink / raw)
  To: Pg Hackers <[email protected]>

While reviewing another patch [1], I noticed an incorrect check in
get_memoize_path.

    if (extra->inner_unique &&
        (inner_path->param_info == NULL ||
         bms_num_members(inner_path->param_info->ppi_serials) <
         list_length(extra->restrictlist)))
        return NULL;

This check is to ensure that, for unique joins, all the restriction
clauses are parameterized to enable the use of Memoize nodes.
However, ppi_clauses includes join clauses available from all outer
rels, not just the current outer rel, while extra->restrictlist only
includes the restriction clauses for the current join.  This means the
check could pass even if a restriction clause isn't parameterized, as
long as another join clause, which doesn't belong to the current join,
is included in ppi_clauses.  It's not very hard to construct a query
that exposes this issue.

create table t (a int, b int);

explain (costs off)
select * from t t0 left join
  (t t1 left join t t2 on t1.a = t2.a
   join lateral
     (select distinct on (a, b) a, b, t0.a+t1.a+t2.a as x from t t3 offset 0) t3
         on t1.a = t3.a and coalesce(t2.b) = t3.b)
  on t0.b = t3.b;
                       QUERY PLAN
---------------------------------------------------------
 Nested Loop Left Join
   ->  Seq Scan on t t0
   ->  Nested Loop
         Join Filter: (COALESCE(t2.b) = t3.b)
         ->  Hash Left Join
               Hash Cond: (t1.a = t2.a)
               ->  Seq Scan on t t1
               ->  Hash
                     ->  Seq Scan on t t2
         ->  Subquery Scan on t3
               Filter: ((t0.b = t3.b) AND (t1.a = t3.a))
               ->  Unique
                     ->  Sort
                           Sort Key: t3_1.a, t3_1.b
                           ->  Seq Scan on t t3_1
(15 rows)

Consider the join to t3.  It is a unique join, and not all of its
restriction clauses are parameterized.  Despite this, the check still
passes.

Interestingly, although the check passes, no Memoize nodes are added
on top of t3's paths because paraminfo_get_equal_hashops insists that
all ppi_clauses must satisfy clause_sides_match_join (though I
actually question whether this is necessary, but that's a separate
issue).  However, this does not justify the check being correct.

Hence, I propose the attached patch for the fix.

BTW, there is a XXX comment there saying that maybe we can make the
remaining join quals part of the inner scan's filter instead of the
join filter.  I don't think this is possible in all cases.  In the
above query, 'coalesce(t2.b) = t3.b' cannot be made part of t3's scan
filter, according to join_clause_is_movable_into.  So I removed that
comment in the patch while we're here.

Any thoughts?

Do you mean this check is designed to work in conjunction with the
clause_sides_match_join check in paraminfo_get_equal_hashops?  I would
consider this a very poor design.  The purpose of this check is simply
to verify whether all restriction clauses are parameterized.  I don't
understand why it needs to depend on paraminfo_get_equal_hashops in
such an unexpected way to function correctly.  I can't see any
advantage to this design, other than that it's prone to bugs.
Moreover, in the case where not all restriction clauses are
parameterized, why waste CPU cycles running all the code after the
check only for paraminfo_get_equal_hashops to catch it later?
Additionally, I couldn't find any comments explaining this unusual
behavior, either in the check itself or in paraminfo_get_equal_hashops.

Thanks
Richard

Here is an updated patch with a commit message.  Regarding
backporting, I'm inclined not to, given the lack of field reports.
Any objections to pushing it?

Thanks

Subject: [PATCH v2] Fix an incorrect check in get_memoize_path

Memoize typically marks cache entries as complete after fully scanning
the inner side of a join.  However, in the case of unique joins, we
skip to the next outer tuple as soon as the first matching inner tuple
is found, leaving no opportunity to scan the inner side to completion.
To work around that, we mark cache entries as complete after fetching
the first matching inner tuple in unique joins.

This approach is only safe when all of the join's restriction clauses
are parameterized; otherwise, there is no guarantee that reading just
one tuple from the inner side is sufficient.

Currently, we check for this by verifying that the number of clauses
in ppi_clauses is no less than the number of the join's restriction
clauses.  However, this check isn't entirely reliable, as ppi_clauses
includes join clauses available from all outer rels, not just the
current outer rel.  This means the check could pass even if a
restriction clause isn't parameterized, as long as another join
clause, which doesn't belong to the current join, is included in
ppi_clauses.

To fix this, we explicitly check whether each restriction clause of
the current join is present in ppi_clauses.

While we're here, remove the XXX comment from the modified code, as
it's not justified; in certain cases, it's not possible to move a join
clause to the inner side.

This is arguably a bugfix, but no backpatch given the lack of field
reports.

v18 is now in feature freeze, but not code freeze, so bug fixes are
still allowed.  I've pushed this patch after adding the "Reviewed-by"
tags.

Thanks
