done along that line.

executing a statement that fires triggers. Formerly this time was
included in "Total runtime" but not otherwise accounted for.
As a side benefit, we avoid re-opening relations when firing non-deferred
AFTER triggers, because the trigger code can re-use the main executor's
ResultRelInfo data structure.

This restores the system's ability to warn about leaks to what it was

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.
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.

currently does. This is now the default Win32 wal sync method because
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.

explicit paths, so that the log can be replayed in a data directory
with a different absolute path than the original had. To avoid forcing
initdb in the 8.0 branch, continue to accept the old WAL log record
types; they will never again be generated however, and the code can be
dropped after the next forced initdb. Per report from Oleg Bartunov.
We still need to think about what it really means to WAL-log CREATE
TABLESPACE commands: we more or less have to put the absolute path
into those, but how to replay in a different context??
