Remove the restriction originally coded into optimize_minmax_aggregates() that
MIN/MAX not be converted to use an index if the query WHERE clause contains
any volatile functions or subplans.
I had originally feared that the conversion might alter the behavior of such a
query with respect to a volatile function. Well, so it might, but only in the
sense that the function would get evaluated at a subset of the table rows
rather than all of them --- and we have never made any such guarantee anyway.
(For instance, we don't refuse to use an index for an ordinary non-aggregate
query when one of the non-indexable filter conditions contains a volatile
function.)
The prohibition against subplans was because of worry that that case wasn't
adequately tested, which it wasn't, but it turns out to be possible to make
8.1 fail anyway:
regression=# select o.ten, (select max(unique2) from tenk1 i where ten = o.ten
or ten = (select f1 from int4_tbl limit 1)) from tenk1 o;
ERROR: direct correlated subquery unsupported as initplan
This is due to bogus code in SS_make_initplan_from_plan (it's an initplan,
ergo it can't have any parParams). Having fixed that, we might as well allow
subplans as well as initplans.

Remove unused function SSL_CTX_set_tmp_dh_callback() from libpq:
In the SSL code in libpq it does some processing with DH parameters:
SSL_CTX_set_tmp_dh_callback()
This function is marked as server use only[1], the client always uses
the DH parameters in the server, so all the code in the client dealing
with the DH parameters is useless. This patch removes it.
It's not clear why the code was added in the first place, it's been
there almost since the beginning[2]. At the time there was a suggestion
of merging the front-end and backend SSL code, but looking at the
changes since, that seems unlikely.
As a further example, the s_server program allows you to specify DH
params, but s_client doesn't. In the GnuTLS documentation under
gnutls_dh_params_generate2() it says[3]:
Also note that the DH parameters are only useful to servers. Since
clients use the parameters sent by the server, it's of no use to call
this in client side.

For syntax that isn't uniquely ISO or PG syntax, like '1' or

Remove from TODO ability to edit pg_hba.conf, but add GRANT connection
permission item:
< o %Allow pg_hba.conf settings to be controlled via SQL
> o %Allow per-database permissions to be set via GRANT
< This would add a function to load the SQL table from
< pg_hba.conf, and one to writes its contents to the flat file.
< The table should have a line number that is a float so rows
< can be inserted between existing rows, e.g. row 2.5 goes
< between row 2 and row 3.
> Allow database connection checks based on GRANT rules in
> addition to the existing access checks in pg_hba.conf.

Add some optional code (conditionally compiled under #ifdef LWLOCK_STATS)
to track the number of LWLock acquisitions and the number of times we
block waiting for an LWLock, on a per-process basis. After having needed
this twice in the past few months, seems like it should go into CVS.

Eliminate some no-longer-needed workarounds for palloc's old behavior
of rejecting palloc(0). Also, tweak like_selectivity() to avoid assuming
the presented pattern is nonempty; although that assumption is valid,
it doesn't really help much, and the new coding is more correct anyway
since it properly handles redundant wildcards. In combination these
changes should eliminate a Coverity warning noted by Martijn.

Add "retry another address" log message on statistics collector socket
failure, to reduce confusion in the log file.

Ensure that we validate the page header of the first page of a WAL file
whenever we start to read within that file. The first page carries
extra identification information that really ought to be checked, but
as the code stood, this was only checked when we switched sequentially
into a new WAL file, or if by chance the starting checkpoint record was
within the first page. This patch ensures that we will detect bogus
'long header' information before we start replaying the WAL sequence.

Recognize __ppc64__, which seems to be Apple's spelling of the predefined
symbol for PPC64 hardware. I hadn't known that Apple supported PPC64 at
all, but darn if there aren't 64-bit variant libraries in OS X as well
as support in their gcc.
