Still, I see zero references to _bt_binsrch(). Not one. Even if there was only one non-meta page (i.e. pre-first-root-split), and regardless of whether this was a read or a write to the B-Tree, there'd still be some call there as the B-Tree was initially scanned (before _bt_next() calls, of which I also see none). -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
