Note that this is *not* what was happening in 8.2. There it was casting them to text and doing a text comparison. In the case of integer and equality they're probably equivalent. However < and > will behave quite differently. That's why the casts disappeared -- you probably weren't running the queries you thought you were running in 8.2 and previously. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com Get trained by Bruce Momjian - ask me about EnterpriseDB's PostgreSQL training!
