overly strong lock on pg_depend, and it wasn't closing the rel when done.
The latter bug was masked by the ResourceOwner code, which is something
that should be changed.

Correct one mis-setting of freeval (which could at worst leak a few bytes
until the trigger exits, so it's no big deal).

since it is included in libpq, the former name polluted application

never-yet-vacuumed relation.  This restores the pre-8.0 behavior of
avoiding seqscans during initial data loading, while still allowing
reasonable optimization after a table has been vacuumed.  Several
regression test cases revert to 7.4-like behavior, which is probably
a good sign.  Per gripes from Keith Browne and others.

we perfer o_datasync to fsync.

Also, change Win32 fsync to a new wal sync method called
fsync_writethrough because that is the behavior of _commit, which is
what is used for fsync on Win32.

ExclusiveLock rather than AccessExclusiveLock. This will allow concurrent
SELECT queries to proceed on the table. Per discussion with Andrew at
