Actually, this is wrong. On further review, by the time I had changed the function definition, the data in the test server I was querying had likely changed enough for the performance to change. That duped me into thinking I had found a work-around. I can no longer reproduce any performance improvement in this manner. mark -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
