When the rewriter converts an RTE_RELATION RTE for a view into
an RTE_SUBQUERY RTE containing the view's defining query, leave
the relid field alone instead of zeroing it. This allows the
planner to tell that the subquery came from a view rather than
having been written in-line, which is needed to support an
upcoming planner bug fix. We cannot change the behavior of the
outfuncs/readfuncs code in released branches, so the relid field
will not survive in plans passed to parallel workers; therefore
this info should not be relied on in the executor.
This back-patches a portion of the data structure definitional
changes made in v16 and up by commit 47bb9db75. It's being
committed separately for visibility in the commit log, but
with luck it will not actually matter to anyone. While it's
not inconceivable that this change will break code expecting
relid to be zero in a subquery RTE, we can hope that such code
has already been adjusted to cope with v16 and up.

The function calls GetLatestSnapshot() to acquire a fresh snapshot,
makes it active, and was meant to pass it to table_tuple_lock(), but
instead called GetLatestSnapshot() again to acquire yet another
snapshot. It was harmless because the heap AM and all other known
table AMs ignore the 'snapshot' argument anyway, but let's be tidy.
In the long run, this perhaps should be redesigned so that snapshot
was not needed in the first place. The table AM API uses TID +
snapshot as the unique identifier for the row version, which is
questionable when the row came from an index scan with a Dirty
snapshot. You might lock a different row version when you use a
different snapshot in the table_tuple_lock() call (a fresh MVCC
snapshot) than in the index scan (DirtySnapshot). However, in the heap
AM and other AMs where the TID alone identifies the row version, it
doesn't matter. So for now, just fix the obvious albeit harmless bug.
This has been wrong ever since the table AM API was introduced in
commit 5db6df0c01, so backpatch to all supported versions.

If a GIN index search had a lot of search keys (for example,
"jsonbcol ?| array[]" with tens of thousands of array elements),
both ginFillScanKey() and startScanKey() took O(N^2) time.
Worse, those loops were uncancelable for lack of CHECK_FOR_INTERRUPTS.
The problem in ginFillScanKey() is the brute-force search key
de-duplication done in ginFillScanEntry(). The most expedient
solution seems to be to just stop trying to de-duplicate once
there are "too many" search keys. We could imagine working harder,
say by using a sort-and-unique algorithm instead of brute force
compare-all-the-keys. But it seems unlikely to be worth the trouble.
There is no correctness issue here, since the code already allowed
duplicate keys if any extra_data is present.
The problem in startScanKey() is the loop that attempts to identify
the first non-required search key. In the submitted test case, that
vainly tests all the key positions, and each iteration takes O(N)
time. One part of that is that it's reinitializing the entryRes[]
array from scratch each time, which is entirely unnecessary given
that the triConsistentFn isn't supposed to scribble on its input.
We can easily adjust the array contents incrementally instead.
The other part of it is that the triConsistentFn may itself take
O(N) time (and does in this test case). This is all extremely
brute force: in simple cases with AND or OR semantics, we could
know without any looping whatever that all or none of the keys
are required. But GIN opclasses don't have any API for exposing
that knowledge, so at least in the short run there is little to
be done about that. Put in a CHECK_FOR_INTERRUPTS so that at
least the loop is cancelable.
These two changes together resolve the primary complaint that
the test query doesn't respond promptly to cancel interrupts.
Also, while they don't completely eliminate the O(N^2) behavior,
they do provide quite a nice speedup for mid-sized examples.

If a domain type has a default, adding a column of that type (without
any explicit DEFAULT clause) failed to install the domain's default
value in existing rows, instead leaving the new column null. This
is unexpected, and it used to work correctly before v11. The cause
is confusion in the atthasmissing mechanism about which default value
to install: we'd only consider installing an explicitly-specified
default, and then we'd decide that no table rewrite is needed.
To fix, take the responsibility for filling attmissingval out of
StoreAttrDefault, and instead put it into ATExecAddColumn's existing
logic that derives the correct value to fill the new column with.
Also, centralize the logic that determines the need for
default-related table rewriting there, instead of spreading it over
four or five places.
In the back branches, we'll leave the attmissingval-filling code
in StoreAttrDefault even though it's now dead, for fear that some
extension may be depending on that functionality to exist there.

There is a race condition between "GRANT role" and "DROP ROLE",
which allows GRANT to install pg_auth_members entries that refer to
dropped roles. (Commit 6566133c5 prevented that for the grantor
field, but not for the granted or grantee roles.) We'll soon fix
that, at least in HEAD, but pg_dumpall needs to cope with the
situation in case of pre-existing inconsistency. As pg_dumpall
stands, it will emit invalid commands like 'GRANT foo TO ""',
which causes pg_upgrade to fail. Fix it to emit warnings and skip
those GRANTs, instead.
There was some discussion of removing the problem by changing
dumpRoleMembership's query to use JOIN not LEFT JOIN, but that
would result in silently ignoring such entries. It seems better
to produce a warning.
Pre-v16 branches already coped with dangling grantor OIDs by simply
omitting the GRANTED BY clause. I left that behavior as-is, although
it's somewhat inconsistent with the behavior of later branches.

This addresses various corner cases in BackgroundPsql:
- On windows stdout and stderr may arrive out of order, leading to errors not
being reported, or attributed to the wrong statement.
To fix, emit the "query-separation banner" on both stdout and stderr and
wait for both.
- Very occasionally the "query-separation banner" would not get removed, because
we waited until the banner arrived, but then replaced the banner plus
newline.
To fix, wait for banner and newline.
- For interactive psql replacing $banner\n is not sufficient, interactive psql
outputs \r\n.
- For interactive psql, where commands are echoed to stdout, the \echo
command, rather than its output, would be matched.
This would sometimes lead to output from the prior query, or wait_connect(),
being returned in the next command.
This also affected wait_connect(), leading to sometimes sending queries to
psql before the connection actually was established.
While debugging these issues I also found that it's hard to know whether a
query separation banner was attributed to the right query. Make that easier by
counting the queries each BackgroundPsql instance has emitted and include the
number in the banner.
Also emit psql stdout/stderr in query() and wait_connect() as Test::More
notes, without that it's rather hard to debug some issues in CI and buildfarm.
As this can cause issues not just to-be-added tests, but also existing ones,
backpatch the fix to all supported versions.

background_psql() in Cluster.pm gains the same "wait" parameter. The

Michael's original commit message:
A newline is not added at the end of an empty query result, causing the
banner of the hardcoded \echo to not be discarded. This would reflect
on scripts that expect an empty result by showing the "QUERY_SEPARATOR"
in the output returned back to the caller, which was confusing.
This commit changes BackgroundPsql::query() so as empty results are able
to work correctly, making the first newline before the banner optional,
bringing more flexibility.
Note that this change affects 037_invalid_database.pl, where three
queries generated an empty result, with the script relying on the data
from the hardcoded banner to exist in the expected output. These
queries are changed to use query_safe(), leading to a simpler script.
The author has also proposed a test in a different patch where empty
results would exist when using BackgroundPsql.

Coverity complained that we weren't doing that, and it's right.
This fix just makes fmtIdEnc() honor the general convention that OOM
causes a PQExpBuffer to become marked "broken", without any immediate
error. In the pretty-unlikely case that we actually did hit OOM here,
the end result would be to return an empty string to the caller,
probably resulting in invalid SQL syntax in an issued command (if
nothing else went wrong, which is even more unlikely). It's tempting
to throw an "out of memory" error if the buffer becomes broken, but
there's not a lot of point in doing that only here and not in hundreds
of other PQExpBuffer-using places in pg_dump and similar callers.
The whole issue could do with some non-time-crunched redesign, perhaps.
This is a followup to the fixes for CVE-2025-1094, and should be
included if cherry-picking those fixes.
Instead of dropping the trailing byte(s) of an invalid or incomplete
multibyte character, replace only the first byte with a known-invalid
sequence, and process the rest normally. This seems less likely to
confuse incautious callers than the behavior adopted in 5dc1e42b4.
While we're at it, adjust PQescapeStringInternal to produce at most
one bleat about invalid multibyte characters per string. This
matches the behavior of PQescapeInternal, and avoids the risk of
producing tons of repetitive junk if a long string is simply given
in the wrong encoding.

In 5dc1e42b4f I fixed bugs in various escape functions, unfortunately as part
of that I introduced a new bug in PQescapeLiteral()/PQescapeIdentifier(). The
bug is that I made PQescapeInternal() just use strlen(), rather than taking
the specified input length into account.
That's bad, because it can lead to including input that wasn't intended to be
included (in case len is shorter than null termination of the string) and
because it can lead to reading invalid memory if the input string is not null
terminated.

a) for escape functions with length support, append data that should not be
escaped and check that it is not
b) add valgrind requests to detect access of bytes that should not be touched

no encoding-aware processing will happen on them.

- Trailing incomplete multi-byte characters are handled sensibly
- Escaped strings are parsed as single statement by psql's parser (which

Functions which can report errors now return an error in more cases than
before. Functions that cannot report errors now replace invalid input bytes
