I still think a small tqual.c maintained cache of hint bits will effectively eliminate hint bit i/o issues surrounding bulk loads. Tom fired a shot across the bow regarding the general worthiness of that technique though (see: http://postgresql.1045698.n5.nabble.com/Process-local-hint-bit-cache-td4270229.html) :(. I can rig up a cleaned up version of the patch pretty easily...it's a local change and fairly simple. I don't think there is any way to remove the hint bits without suffering some other problem. merlin -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
