Probably questions best asked on hackers but I figure many are represented here. Will there ever be a release where a dump-restore is not necessary? Perhaps, at least, minor releases (e.g. 9.0 to 9.1) will not require a dump-restore? >From 9.0 Release Notes: E.1.2. Migration to Version 9.0 A dump/restore using pg_dump, or use of pg_upgrade, is required for those wishing to migrate data from any previous release. Version 9.0 contains a number of changes that selectively break backwards compatibility in order to support new features and code quality improvements. Also, users who make extensive use of PL/pgSQL, Point-In-Time Recovery (PITR), and Warm Standby should test their solutions because of slight user-visible changes in these areas. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
