A minor release (where the version number doesn't change before the second dot) never requires a dump and restore. There is sometimes a need to do some cleanup work; for example, if a bug is fixed which could corrupt a particular type of index, the release notes may recommend rebuilding all indexes of that type to repair any damage which may have occurred before the bug was fixed. http://www.postgresql.org/support/versioning/ -Kevin -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
