Per my previous mail, I think we can change things so that Index tuples effectively record that in all relevant cases. i.e., in what I called separator key index tuples -- high key tuples in leaf pages, and all internal page index tuples (high keys and downlinks/internal items). We already store a minus infinity downlink on internal pages, which doesn't bother diagnostic tools at all, despite being its own special case without real Datum values. -- 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
