number of palloc calls.  This has a salutory impact on plpgsql operations
with record variables (which create and destroy tupdescs constantly)
and probably helps a bit in some other cases too.

The old codes continue to work.

Too much space is allocated for tablespace file path, I guess the
directory name used to be "pg_tablespaces" instead of "pg_tblspc" at
some point.

on-the-fly, and thereby avoid blowing out memory when the planner has
underestimated the hash table size.  Hash join will now obey the
work_mem limit with some faithfulness.  Per my recent proposal
(hash aggregate part isn't done yet though).

the freelist, plus per-buffer spinlocks that protect access to individual
shared buffer headers.  This requires abandoning a global freelist (since
the freelist is a global contention point), which shoots down ARC and 2Q
as well as plain LRU management.  Adopt a clock sweep algorithm instead.
Preliminary results show substantial improvement in multi-backend situations.

of AND and OR clauses.  The key point here is that an OR on the
predicate side has to be treated gingerly: we may be able to prove
that the OR is implied even when no one of its components is implied.
For example (x OR y) implies (x OR y OR z) even though no one of x,
y, or z can be individually proven.  This code handles both the
example shown recently by Sergey Koshcheyev and the one shown last
October by Dawid Kuroczko.

no held locks.  This maintains the invariant that proclocks are present
only for procs that are holding or awaiting a lock; when this is not
true, LockRelease will fail.  Per report from Stephen Clouse.

by a simple indexscan on such an index, so there's no point in considering
them.  Fixes overoptimism in a patch I applied last October.

I broke it for OR'd index predicates in a fit of code cleanup last summer.
