It's unlikely that any config settings are causing coredumps. Did you backup and rebuild the database during the upgrade procedure? If not, this could be your problem. You can't run 7.4 on a 7.2 database. Otherwise, you may want to provide more details about the host system and the upgrade procedures you followed. -- Bill Moran Potential Technologies http://www.potentialtech.com ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faqs/FAQ.html
