As in commits 6301c3ada and e9d9ba2a4, avoid doing repetitive
list_delete_first() operations, since that would be expensive when
there are many files waiting to be unlinked. This is a slightly
larger change than in those cases. We have to keep the list state
valid for calls to AbsorbSyncRequests(), so it's necessary to invent a
"canceled" field instead of immediately deleting PendingUnlinkEntry
entries. Also, because we might not be able to process all the
entries, we need a new list primitive list_delete_first_n().
list_delete_first_n() is almost list_copy_tail(), but it modifies the
input List instead of making a new copy. I found a couple of existing
uses of the latter that could profitably use the new function. (There
might be more, but the other callers look like they probably shouldn't
overwrite the input List.)
As before, back-patch to v13.

In the same spirit as 6301c3ada, fix some more places where we were
using list_delete_first() in a loop and thereby risking O(N^2)
behavior. It's not clear that the lists manipulated in these spots
can get long enough to be really problematic ... but it's not clear
that they can't, either, and the fixes are simple enough.

The opclass parameter Datums from the old index are fetched in the same
way as for predicates and expressions, by grabbing them directly from
the system catalogs. They are then copied into the new IndexInfo that
will be used for the creation of the new copy.
This caused the new index to be rebuilt with default parameters rather
than the ones pre-defined by a user. The only way to get back a new
index with correct opclass parameters would be to recreate a new index
from scratch.
The issue has been introduced by 911e702.

Commit d168b66682, which overhauled index deletion, added a
pg_unreachable() to the end of a sort comparator used when sorting heap
TIDs from an index page. This allows the compiler to apply
optimizations that assume that the heap TIDs from the index AM must
always be unique.

Commits fdd965d07 and 3cd9c3b92 tested CREATE INDEX CONCURRENTLY by
launching two separate pgbench runs concurrently. This was needed so
that only a single client thread would run CREATE INDEX CONCURRENTLY,
avoiding deadlock between two CICs. However, there's a better way,
which is to use an advisory lock to prevent concurrent CICs. That's
better in part because the test code is shorter and more readable, but
mostly because it automatically scales things to launch an appropriate
number of CICs relative to the number of INSERT transactions.
As committed, typically half to three-quarters of the CIC transactions
were pointless because the INSERT transactions had already stopped.
In passing, remove background_pgbench, which was added to support
these tests and isn't needed anymore. We can always put it back

The purpose of commit 8a54e12a38d1545d249f1402f66c8cde2837d97c was to
fix this, and it sufficed when the PREPARE TRANSACTION completed before
the CIC looked for lock conflicts. Otherwise, things still broke. As
before, in a cluster having used CIC while having enabled prepared
transactions, queries that use the resulting index can silently fail to
find rows. It may be necessary to reindex to recover from past
occurrences; REINDEX CONCURRENTLY suffices. Fix this for future index

I think when I added this assertion (in commit 8f889b108), I was only
thinking of the use of transformExpressionList at top level of INSERT

certainly occur in an UPDATE targetlist, so it's inappropriate to
suppose that p_multiassign_exprs must be empty. Besides, since the
input is not expected to contain ResTargets, there's no reason it
should contain MultiAssignRefs either. Hence this code need not
be concerned about the state of p_multiassign_exprs, and we should

The grammar of this command run on indexes with column names has always
been authorized by the parser, and it has never been documented.
Since 911e702, it is possible to define opclass parameters as of CREATE
INDEX, which actually broke the old case of ALTER INDEX/TABLE where
relation-level parameters n_distinct and n_distinct_inherited could be
defined for an index (see 76a47c0 and its thread where this point has
been touched, still remained unused). Attempting to do that in v13~
would cause the index to become unusable, as there is a new dedicated
code path to load opclass parameters instead of the relation-level ones
previously available. Note that it is possible to fix things with a
manual catalog update to bring the relation back online.
This commit disables this command for now as the use of column names for
indexes does not make sense anyway, particularly when it comes to index
expressions where names are automatically computed. One way to properly
support this case properly in the future would be to use column numbers
when it comes to indexes, in the same way as ALTER INDEX .. ALTER COLUMN
.. SET STATISTICS.
Partitioned indexes were already blocked, but not indexes. Some tests
are added for both cases.
There was some code in ANALYZE to enforce n_distinct to be used for an
index expression if the parameter was defined, but just remove it for
now until/if there is support for this (note that index-level parameters
never had support in pg_dump either, previously), so this was just dead
code.

During a replication slot creation, an ERROR generated in the same
transaction as the one creating a to-be-exported snapshot would have
left the backend in an inconsistent state, as the associated static
export snapshot state was not being reset on transaction abort, but only
on the follow-up command received by the WAL sender that created this
snapshot on replication slot creation. This would trigger inconsistency
failures if this session tried to export again a snapshot, like during
the creation of a replication slot.
Note that a snapshot export cannot happen in a transaction block, so
there is no need to worry resetting this state for subtransaction
aborts. Also, this inconsistent state would very unlikely show up to
users. For example, one case where this could happen is an
out-of-memory error when building the initial snapshot to-be-exported.

Avoid calling contrib/amcheck functions with relations that are
unsuitable for checking. Specifically, don't attempt verification of
temporary relations, or indexes whose pg_index entry indicates that the
index is invalid, or not ready.
These relations are not supported by any of the contrib/amcheck
functions, for reasons that are pretty fundamental. For example, the
implementation of REINDEX CONCURRENTLY can add its own "transient"
pg_index entries, which has rather unclear implications for the B-Tree
verification functions, at least in the general case -- so they just
treat it as an error. It falls to the amcheck caller (in this case
pg_amcheck) to deal with the situation at a higher level.
pg_amcheck now simply treats these conditions as additional "visibility
concerns" when it queries system catalogs. This is a little arbitrary.

This fixes a set of issues that cause different breakages or annoyances
when using pg_upgrade's test.sh to do upgrades across different major
versions:
- test.sh is completely broken when using v14 as new version because of
the removal of testtablespace/ as Makefile rule. Older versions of
pg_regress don't support --make-tablespacedir, blocking the creation of
the tablespace. In order to fix that, it is simple enough to create
those directories in the script itself, but only do that when an old
version is involved. This fix is needed on HEAD and REL_14_STABLE.
- The script would fail when using PG <= v11 as old version because of
WITH OIDS relations not supported in v12. In order to fix this, this
steals a method from the buildfarm that uses a DO block to change all
the relations marked as WITH OIDS, allowing pg_upgrade to pass. This is
more portable than using ALTER TABLE queries on the relations causing
issues. This is fixed down to v12, and authored originally by Andrew
Dunstan.
- Not using --extra-float-digits=0 with v11 as old version causes
a lot of diffs in the dumps, making the whole unreadable. This gets
only done when using v11 as old version. This is fixed down to v12.
The buildfarm code uses that already.
Note that the addition of --wal-segsize and --allow-group-access breaks
the script when using v10 or older at initdb time as these got added in
11. 10 would be EOL'd next year and nobody has complained about those
problems yet, so nothing is done about that. This means that this
commit fixes upgrade tests using test.sh with v11 as minimum older
version, up to HEAD, and that it is enough to apply this change down to
12. The old and new dumps still generate diffs, still require manual
checks, and more could be done to reduce the noise, but this allows the
tests to run with a rather minimal amount of them.
I have tested this commit and test.sh with v11 as minimum across all the
branches where this is applied. Note that this commit has no impact on
the normal pg_upgrade test run with a simple "make check".
