Fix race condition in relcache init file invalidation (Tom Lane)

<para>
There was a window wherein a new backend process could read a stale init

Fix memory leak at end of a GiST index scan (Tom Lane)
</para>
<para>
Commands that perform many separate GiST index scans, such as
verification of a new GiST-based exclusion constraint on a table
already containing many rows, could transiently require large amounts of
memory due to this leak.

Fix array- and path-creating functions to ensure padding bytes are
zeroes (Tom Lane)

Fix typo in <function>pg_srand48</> seed initialization (Andres Freund)
</para>
<para>
This led to failure to use all bits of the provided seed. This function
is not used on most platforms (only those without <function>srandom</>),
and the potential security exposure from a less-random-than-expected
seed seems minimal in any case.
