<para>
Ignore the <literal>CONCURRENTLY</literal> option when performing an
index creation, drop, or rebuild on a temporary table (Michael
Paquier, Heikki Linnakangas, Andres Freund)
</para>
<para>
This avoids strange failures if the temporary table has
an <literal>ON COMMIT</literal> action. There is no benefit in
using <literal>CONCURRENTLY</literal> for a temporary table anyway,
since other sessions cannot access the table, making the extra
processing pointless.

Fix BRIN index logic to support hypothetical BRIN indexes
(Julien Rouhaud, Heikki Linnakangas)
</para>
<para>
Previously, if an <quote>index adviser</quote> extension tried to
get the planner to produce a plan involving a hypothetical BRIN
index, that would fail, because the BRIN cost estimation code would
always try to physically access the index's metapage. Now it checks
to see if the index is only hypothetical, and uses default
assumptions about the index parameters if so.

Transmit incoming <command>NOTIFY</command> messages to the client
before sending <literal>ReadyForQuery</literal>, rather than after
(Tom Lane)
</para>
<para>
This change ensures that, with libpq and other client libraries that
act similarly to it, any notifications received during a transaction
will be available by the time the client thinks the transaction is
complete. This probably makes no difference in practical
applications (which would need to cope with asynchronous
notifications in any case); but it makes it easier to build test
cases with reproducible behavior.

Avoid memory leak in sanity checks for <quote>slab</quote> memory
contexts (Tomas Vondra)
</para>
<para>
This isn't an issue for production builds, since they wouldn't
ordinarily have memory context checking enabled; but the leak could
be quite severe in a debug build.

Fix multiple statistics entries reported by the LWLock statistics

</para>
<para>
The LWLock statistics code (which is not built by default; it
requires compiling with <option>-DLWLOCK_STATS</option>)
could report multiple entries for the same LWLock and backend
process, as a result of faulty hashtable key creation.

On Windows, retry a few times after
an <literal>ERROR_ACCESS_DENIED</literal> file access failure
(Alexander Lakhin, Tom Lane)
</para>
<para>
This helps cope with cases where a file open attempt fails because
the targeted file is flagged for deletion but not yet actually gone.
<application>pg_ctl</application>, for example, frequently failed
with such an error when probing to see if the postmaster had shut
down yet.
