Fix replay of <command>CREATE DATABASE</command> WAL
records on standby servers
(Kyotaro Horiguchi, Asim R Praveen, Paul Guo)
</para>
<para>
Standby servers may encounter missing tablespace directories
when replaying database-creation WAL records. Prior to this
patch, a standby would fail to recover in such a case;
however, such directories could be legitimately missing.
Create the tablespace (as a plain directory), then check that it
has been dropped again once replay reaches a consistent state.

<para>
Support <quote>in place</quote> tablespaces
(Thomas Munro, Michael Paquier, &Aacute;lvaro Herrera)
</para>
<para>
Normally a Postgres tablespace is a symbolic link to a directory on
some other filesystem. This change allows it to just be a plain
directory. While this has no use for separating tables onto
different filesystems, it is a convenient setup for testing.
Moreover, it is necessary to support the <command>CREATE
DATABASE</command> replay fix, which transiently creates a missing
tablespace as an <quote>in place</quote> tablespace.

Fix permissions checks in <command>CREATE INDEX</command> (Nathan
Bossart, Noah Misch)
</para>
<para>
The fix for CVE-2022-1552 caused <command>CREATE INDEX</command> to
apply the table owner's permissions while performing lookups of
operator classes and other objects, where formerly the calling
user's permissions were used. This broke dump/restore scenarios,
because <application>pg_dump</application> issues <command>CREATE
INDEX</command> before re-granting permissions.

<para>
In extended query protocol, force an immediate commit
after <command>CREATE DATABASE</command> and other commands that
can't run in a transaction block (Tom Lane)
</para>
<para>
If the client does not send a Sync message immediately after such a
command, but instead sends another command, any failure in that
command would lead to rolling back the preceding command, typically
leaving inconsistent state on-disk (such as a missing or extra
database directory). The mechanisms intended to prevent that
situation turn out to work for multiple commands in a simple-Query
message, but not for a series of extended-protocol messages. To
prevent inconsistency without breaking use-cases that work today,
force an implicit commit after such commands.

Fix race condition when checking transaction visibility (Simon Riggs)
</para>
<para>
<function>TransactionIdIsInProgress</function> could
report <literal>false</literal> before the subject transaction is
considered visible, leading to various misbehaviors. The race
condition window is normally very narrow, but use of synchronous
replication makes it much wider, because the wait for a synchronous
replica happens in that window.

Reject <literal>ROW()</literal> expressions and functions

</para>
<para>
Cases with more than about 1600 columns are unsupported, and
have always failed at execution. However, it emerges that some
earlier code could be driven to assertion failures or crashes by
queries with more than 32K columns. Add a parse-time check to
prevent that.

Arrange to clean up after commit-time errors
within <function>SPI_commit()</function>, rather than expecting
callers to do that (Peter Eisentraut, Tom Lane)
</para>
<para>
Proper cleanup is complicated and requires use of low-level
facilities, so it's not surprising that no known caller got it
right. This led to misbehaviors when a PL procedure
issued <command>COMMIT</command> but a failure occurred (such as a
deferred constraint check). To improve matters,
redefine <function>SPI_commit()</function> as starting a new
transaction, so that it becomes equivalent
to <function>SPI_commit_and_chain()</function> except that you get
default transaction characteristics instead of preserving the prior
transaction's characteristics. To make this somewhat transparent
API-wise, redefine <function>SPI_start_transaction()</function> as a
no-op. All known callers of <function>SPI_commit()</function>
immediately call <function>SPI_start_transaction()</function>, so
they will not notice any change. Similar remarks apply
to <function>SPI_rollback()</function>.
</para>
<para>
Also fix PL/Python, which omitted any handling of such errors at all,
resulting in jumping out of the Python interpreter. This is
reported to crash Python 3.11. Older Python releases leak some
memory but seem okay with it otherwise.

Remove misguided SSL key file ownership check

<para>
In the previous minor releases, we copied the server's permission
checking rules for SSL private key files into libpq. But we should
not have also copied the server's file-ownership check. While that
works in normal use-cases, it can result in an unexpected failure
for clients running as root, and perhaps in other cases.
