Remove geqo_random_seed parameter. Having geqo reset the global random()
sequence every time it's called is bogus --- it interferes with user
control over the seed, and actually decreases randomness overall
(because a seed based on time(NULL) is pretty predictable). If you really
want a reproducible result from geqo, do 'set seed = 0' before planning
a query.

Remove check on source address of a statistics packet. Check was broken

anyway, it seems not worth trying to fix it. Per recent discussions.

load_file() has to remove pre-existing shlibs that match the new file
on either name or inode; otherwise load_external_function() won't do
anything. At least on Linux, it appears that recompiling a shlib leads
to a new file with a different inode, so the old code failed to detect
a match.
Make all valid uses of the COLLATE clause yield the same result: a syntax
error. There is no point in providing some kind of forward compatibility
now, because no one can tell what a future implementation will look like.

Reimplement hash index locking algorithms, per my recent proposal to
pghackers. This fixes the problem recently reported by Markus KrÌutner
(hash bucket split corrupts the state of scans being done concurrently),
and I believe it also fixes all the known problems with deadlocks in
hash index operations. Hash indexes are still not really ready for prime
time (since they aren't WAL-logged), but this is a step forward.

In _bt_check_unique() loop, don't bother applying _bt_isequal() to
killed items; just skip to the next item immediately. Only check for
key equality when we reach a non-killed item or the end of the index
page. This saves key comparisons when there are lots of killed items,
as for example in a heavily-updated table that's not been vacuumed lately.
Seems to be a win for pgbench anyway.

Cause standalone backend (including bootstrap case) to read the GUC
config file if it exists. This was already discussed as being a good
idea, and now seems the cleanest way to deal with initdb-time failures
on machines with small SHMMAX. (The submitted patches instead modified
initdb.sh to pass the correct sizing parameters, but that would still
leave standalone backends prone to failure later. An admin who needs
to use a standalone backend has enough trouble already, he shouldn't
have to manually configure its shmem settings...)

Several fixes for hash indexes that involve changing the on-disk index
layout; therefore, this change forces REINDEX of hash indexes (though
not a full initdb). Widen hashm_ntuples to double so that hash space
management doesn't get confused by more than 4G entries; enlarge the
allowed number of free-space-bitmap pages; replace the useless bshift
field with a useful bmshift field; eliminate 4 bytes of wasted space
in the per-page special area.

Rewrite hashbulkdelete() to make it amenable to new bucket locking
scheme. A pleasant side effect is that it is *much* faster when deleting
a large fraction of the indexed tuples, because of elimination of
redundant hash_step activity induced by hash_adjscans. Various other
continuing code cleanup.
libpq, talking to an old server, should assume SQL_ASCII as the default
client encoding, because that is what the server will actually use (not
the server encoding).

Preliminary cleanup for hash index code (doesn't attack the locking problem
yet). Fix a couple of bugs that would only appear if multiple bitmap pages
are used, including a buffer reference leak and incorrect computation of bit
indexes. Get rid of 'overflow address' concept, which accomplished nothing
except obfuscating the code and creating a risk of failure due to limited
range of offset field. Rename some misleadingly-named fields and routines,

Refactor code so that to_date() does not call to_timestamp() and then
