In general you don't have to initdb when upgrading to a new point release, and the Release Notes should tell you if it's necessary or not. Sometimes an initdb might be desirable, however, to fix certain catalog problems -- this is the case with 8.0.3, for example. If you don't want to initdb then there's a manual fix procedure: http://www.postgresql.org/docs/8.0/static/release.html#RELEASE-8-0-3 I think the following query shows the version of initdb that initialized the cluster, but somebody please correct me if I'm mistaken: SELECT character_value FROM information_schema.sql_implementation_info WHERE implementation_info_name = 'DBMS VERSION'; The value displayed appears to have been created by set_info_version() in initdb.c. -- Michael Fuhr http://www.fuhr.org/~mfuhr/
