A 5-line patch which improves performance by 40% for any case sounds amazing, but how fragile is that gain? The kind of thing which would be worryign is if runing a query which uses both varchar and some other ambiguous operator causes it to lose all its gain. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com Ask me about EnterpriseDB's RemoteDBA services! ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
