My idea as well, though it looks ugly and it would be a maintenance head-ache (upgrading the index as new transaction types are added would mean "costly" write locks on the table, and we can't rely on manual processes to get it right ... we might need to set up scripts to either upgrade the index or alert us if the index needs upgrading). -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
