docs: update guidelines on when to use GIN and GiST indexes

Backpatch through 9.5

Docs: explain contrib/pg_stat_statements' handling of GC failure.

2015-10-05T16:44:20+00:00

Failure to perform garbage collection now has a user-visible effect, so
explain that and explain that reducing pgss_max is the way to prevent it.
Per gripe from Andrew Dunstan.

Fix insufficiently-portable regression test case.

2015-10-05T16:19:14+00:00

Some of the buildfarm members are evidently miserly enough of stack space
to pass the originally-committed form of this test.  Increase the
requirement 10X to hopefully ensure that it fails as-expected everywhere.

Security: CVE-2015-5288, CVE-2015-5289

Remove outdated comment about relation level autovacuum freeze limits.

2015-10-05T14:51:03+00:00

The documentation for the autovacuum_multixact_freeze_max_age and
autovacuum_freeze_max_age relation level parameters contained:
"Note that while you can set autovacuum_multixact_freeze_max_age very
small, or even zero, this is usually unwise since it will force frequent
vacuuming."
which hasn't been true since these options were made relation options,
instead of residing in the pg_autovacuum table (834a6da4f7).

Remove the outdated sentence. Even the lowered limits from 2596d70 are
high enough that this doesn't warrant calling out the risk in the CREATE
TABLE docs.

Per discussion with Tom Lane and Alvaro Herrera

Backpatch: 9.0- (in parts)

Add regression tests for INSERT/UPDATE+RETURNING

2015-10-05T14:14:51+00:00

This adds regressions tests which are specific to INSERT+RETURNING and
UPDATE+RETURNING to ensure that the SELECT policies are added as
WithCheckOptions (and should therefore throw an error when the policy is
violated).

Per suggestion from Andres.

Back-patch to 9.5 as the prior commit was.

Prevent stack overflow in query-type functions.

2015-10-05T14:06:33+00:00

The tsquery, ltxtquery and query_int data types have a common ancestor.
Having acquired check_stack_depth() calls independently, each was
missing at least one call.  Back-patch to 9.0 (all supported versions).

Prevent stack overflow in container-type functions.

2015-10-05T14:06:33+00:00

A range type can name another range type as its subtype, and a record
type can bear a column of another record type.  Consequently, functions
like range_cmp() and record_recv() are recursive.  Functions at risk
include operator family members and referents of pg_type regproc
columns.  Treat as recursive any such function that looks up and calls
the same-purpose function for a record column type or the range subtype.
Back-patch to 9.0 (all supported versions).

An array type's element type is never itself an array type, so array
functions are unaffected.  Recursion depth proportional to array
dimensionality, found in array_dim_to_jsonb(), is fine thanks to MAXDIM.
