Properly unregister OpenSSL callbacks when libpq is done with
it's connection. This is required for applications that unload
the libpq library (such as PHP) in which case we'd otherwise
have pointers to these functions when they no longer exist.
This needs a bit more testing before we can consider a backpatch,
so not doing that yet.
In passing, remove unused functions in backend/libpq.

Forgot to bump catalog version in the visibility map patch.
Heikki Linnakangas [Wed, 3 Dec 2008 13:05:22 +0000 (13:05 +0000)]
Introduce visibility map. The visibility map is a bitmap with one bit per
heap page, where a set bit indicates that all tuples on the page are
visible to all transactions, and the page therefore doesn't need
vacuuming. It is stored in a new relation fork.
Lazy vacuum uses the visibility map to skip pages that don't need
vacuuming. Vacuum is also responsible for setting the bits in the map.
In the future, this can hopefully be used to implement index-only-scans,
but we can't currently guarantee that the visibility map is always 100%
up-to-date.
In addition to the visibility map, there's a new PD_ALL_VISIBLE flag on
each heap page, also indicating that all tuples on the page are visible to
all transactions. It's important that this flag is kept up-to-date. It
is also used to skip visibility tests in sequential scans, which gives a
small performance gain on seqscans.

wait for the previous instead of the new file to be archived.

Use PG_GETARG_TEXT_PP instead of PG_GETARG_TEXT_P in the new

Change wildcard cerfificate mapping to be much simler - we now only match
the * character at the beginning of a pattern, and it does not match
subdomains.
Since this means we no longer need fnmatch, remove the imported implementation
from port, along with the autoconf check for it.
