+ Fix multiple bugs associated with <command>CREATE INDEX

+ </para>
+
+ <para>
+ Fix <command>CREATE INDEX CONCURRENTLY</> to use

+ Also, fix various other operations to ensure that they ignore
+ invalid indexes resulting from a failed <command>CREATE INDEX

+ on the table before corrective action can be taken to fix or remove

+ <para>
+ Fix multiple bugs associated with <command>CREATE INDEX
+ CONCURRENTLY</> (Andres Freund, Tom Lane)
+ </para>
+
+ <para>
+ Fix <command>CREATE INDEX CONCURRENTLY</> to use
+ in-place updates when changing the state of an index's
+ <structname>pg_index</> row. This prevents race conditions that could
+ cause concurrent sessions to miss updating the target index, thus
+ resulting in corrupt concurrently-created indexes.
+ </para>
+
+ <para>
+ Also, fix various other operations to ensure that they ignore
+ invalid indexes resulting from a failed <command>CREATE INDEX
+ CONCURRENTLY</> command. The most important of these is
+ <command>VACUUM</>, because an auto-vacuum could easily be launched
+ on the table before corrective action can be taken to fix or remove
+ the invalid index.

+ <para>
+ Fix buffer locking during WAL replay (Tom Lane)
+ </para>
+
+ <para>
+ The WAL replay code was insufficiently careful about locking buffers
+ when replaying WAL records that affect more than one page. This could
+ result in hot standby queries transiently seeing inconsistent states,
+ resulting in wrong answers or unexpected failures.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ Fix an error in WAL generation logic for GIN indexes (Tom Lane)
+ </para>
+
+ <para>

+ <para>
+ Properly remove startup process's virtual XID lock when promoting a
+ hot standby server to normal running (Simon Riggs)
+ </para>
+
+ <para>
+ This oversight could prevent subsequent execution of certain
+ operations such as <command>CREATE INDEX CONCURRENTLY</>.

+ Prevent the postmaster from launching new child processes after it's
+ received a shutdown signal (Tom Lane)
+ </para>
+
+ <para>
+ This mistake could result in shutdown taking longer than it should, or
+ even never completing at all without additional user action.

+ Prevent file descriptors for dropped tables from being held open past

+ </para>
+
+ <para>
+ This should reduce problems with long-since-dropped tables continuing
+ to occupy disk space.

+ <listitem>
+ <para>
+ Prevent database-wide crash and restart when a new child process is
+ unable to create a pipe for its latch (Tom Lane)
+ </para>
+
+ <para>
+ Although the new process must fail, there is no good reason to force a
+ database-wide restart, so avoid that. This improves robustness when
+ the kernel is nearly out of file descriptors.
+ </para>
+ </listitem>
+

+ <para>
+ Fix planning of non-strict equivalence clauses above outer joins
+ (Tom Lane)
+ </para>
+
+ <para>
+ The planner could derive incorrect constraints from a clause equating
+ a non-strict construct to something else, for example
+ <literal>WHERE COALESCE(foo, 0) = 0</>
+ when <literal>foo</> is coming from the nullable side of an outer join.

+ <para>
+ Fix partial-row matching in hashed subplans to handle cross-type cases
+ correctly (Tom Lane)
+ </para>
+
+ <para>
+ This affects multicolumn <literal>NOT IN</> subplans, such as
+ <literal>WHERE (a, b) NOT IN (SELECT x, y FROM ...)</>
+ when for instance <literal>b</> and <literal>y</> are <type>int4</>
+ and <type>int8</> respectively. This mistake led to wrong answers
+ or crashes depending on the specific datatypes involved.

+ <listitem>
+ <para>
+ Acquire buffer lock when re-fetching the old tuple for an
+ <literal>AFTER ROW UPDATE/DELETE</> trigger (Andres Freund)
+ </para>
+
+ <para>
+ In very unusual circumstances, this oversight could result in passing
+ incorrect data to a trigger <literal>WHEN</> condition, or to the
+ precheck logic for a foreign-key enforcement trigger. That could
+ result in a crash, or in an incorrect decision about whether to
+ fire the trigger.

+ <para>
+ Ignore incorrect <structname>pg_attribute</> entries for system
+ columns for views (Tom Lane)
+ </para>
+
+ <para>
+ Views do not have any system columns. However, we forgot to
+ remove such entries when converting a table to a view. That's fixed
+ properly for 9.3 and later, but in previous branches we need to defend
+ against existing mis-converted views.

+
+ <para>
+ While this mistake had no particular impact on
