+ Avoid potential deadlock during catalog cache initialization
+ (Nikhil Sontakke)
+ </para>
+
+ <para>
+ In some cases the cache loading code would acquire share lock on a
+ system index before locking the index's catalog. This could deadlock
+ against processes trying to acquire exclusive locks in the other,
+ more standard order.

+ <para>
+ Fix dangling-pointer problem in <literal>BEFORE ROW UPDATE</> trigger
+ handling when there was a concurrent update to the target tuple
+ (Tom Lane)
+ </para>
+
+ <para>
+ This bug has been observed to result in intermittent <quote>cannot
+ extract system attribute from virtual tuple</> failures while trying to
+ do <literal>UPDATE RETURNING ctid</>. There is a very small probability
+ of more serious errors, such as generating incorrect index entries for
+ the updated tuple.

+ Support use of dlopen() in FreeBSD and OpenBSD on MIPS (Tom Lane)
+ </para>
+
+ <para>
+ There was a hard-wired assumption that this system function was not

+ instead, since more recent versions have it.
