Enforce standard locking protocol for TOAST table updates, to prevent
problems with <command>REINDEX CONCURRENTLY</command> (Michael Paquier)
</para>
<para>
If applied to a TOAST table or TOAST table's index, <command>REINDEX
CONCURRENTLY</command> tended to produce a corrupted index. This
happened because sessions updating TOAST entries released
their <literal>ROW EXCLUSIVE</literal> locks immediately, rather
than holding them until transaction commit as all other updates do.
The fix is to make TOAST updates hold the table lock according to the
normal rule. Any existing corrupted indexes can be repaired by
reindexing again.

Fix index-only scan plans for cases where not all index columns can
be returned (Tom Lane)
</para>
<para>
If an index has both returnable and non-returnable columns, and one
of the non-returnable columns is an expression using a table column
that appears in a returnable index column, then a query using that
expression could result in an index-only scan plan that attempts to
read the non-returnable column, instead of recomputing the
expression from the returnable column as intended. The
non-returnable column would read as NULL, resulting in wrong query
results.

Fix startup of a physical replica to tolerate transaction ID
wraparound (Abhijit Menon-Sen, Tomas Vondra)
</para>
<para>
If a replica server is started while the set of active transactions
on the primary crosses a wraparound boundary (so that there are some
newer transactions with smaller XIDs than older ones), the replica
would fail with <quote>out-of-order XID insertion in
KnownAssignedXids</quote>. The replica would retry, but could never
get past that error.

Remove lexical limitations for SQL commands issued on a logical

The walsender process would fail for a SQL command containing an
unquoted semicolon, or with dollar-quoted literals containing odd
numbers of single or double quote marks, or when the SQL command
starts with a comment. Moreover, faulty error recovery could lead
to unexpected errors in later commands too.

Build extended statistics for partitioned tables (Justin Pryzby)
</para>
<para>
A previous bug fix disabled building of extended statistics for
old-style inheritance trees, but it also prevented building them for
partitioned tables, which was an unnecessary restriction.
This change allows <command>ANALYZE</command> to compute values for
statistics objects for partitioned tables. (But note that
autovacuum does not process partitioned tables as such, so you must
periodically issue manual <command>ANALYZE</command> on the
partitioned table if you want to maintain such statistics.)

Ignore extended statistics for inheritance trees (Justin Pryzby)
</para>
<para>
Currently, extended statistics values are only computed locally for
each table, not for entire inheritance trees. However the values
were mistakenly consulted when planning queries across inheritance
trees, possibly resulting in worse-than-default estimates.

Avoid calling <function>strerror</function>
from <application>libpq</application>'s <function>PQcancel</function>
function (Tom Lane)
</para>
<para>
<function>PQcancel</function> is supposed to be safe to call from a
signal handler, but <function>strerror</function> is not safe. The
faulty usage only occurred in the unlikely event of failure to
send the cancel message to the server, perhaps explaining the lack
of reports.

This agrees with the documented behavior, and avoids probable

included in the password prompt.

Fix results of index-only scans
on <filename>contrib/btree_gist</filename> indexes
on <type>char(<replaceable>N</replaceable>)</type> columns (Tom Lane)
</para>
<para>
Index-only scans returned column values with trailing spaces
removed, which is not the expected behavior. That happened because
that's how the data was stored in the index. This fix changes the
code to store <type>char(<replaceable>N</replaceable>)</type> values
with the expected amount of space padding.
The behavior of such an index will not change immediately unless
you <command>REINDEX</command> it; otherwise space-stripped values
will be gradually replaced over time during updates. Queries that
do not use index-only scan plans will be unaffected in any case.

Change <application>configure</application> to use
Python's <application>sysconfig</application> module, rather than
the deprecated <application>distutils</application> module, to
determine how to build PL/Python (Peter Eisentraut, Tom Lane, Andres
Freund)
</para>
<para>
With Python 3.10, this
avoids <application>configure</application>-time warnings
about <application>distutils</application> being deprecated and
scheduled for removal in Python 3.12. Presumably, once 3.12 is
out, <literal>configure --with-python</literal> would fail
altogether. This future-proofing does come at a
cost: <application>sysconfig</application> did not exist before
Python 2.7, nor before 3.2 in the Python 3 branch, so it is no
longer possible to build PL/Python against long-dead Python
versions.
