However, there's no guarantee that 9.5 or 9.6 will be able to _restore_ dumps made with Pg10's pg_dumpall and pg_dump. We don't have any output-compatibility in pg_dump to limit it to features from some $older_release . But ... you can always backpatch it yourself into older Pg and build your own pg_dump and pg_dumpall. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
