Could you just replay WAL updates? I.e. have two copies of the database on each device, one as the mirror of the "master" and one as the "live" version. When you need to push the changes out, just push out the WAL updates, dump the "live" version, copy the "master" into a new "live" version and then replay the new WAL records. Depends on how much disk space you have I guess. -- Sam http://samason.me.uk/ -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
