Hello,
Forgive me if this has been discussed before (or if it sounds absurd)
Upgrading large postgres databases (100GB+) takes awfully long time when
doing dump/restore. I was wondering if this process can be optimized by
directly dumping to a new version of Pg database directly on another server
without having to dump to the filesystem and then restore it.
pg_dump on new server might look something like,
pg_dump <options> -h <old server> -h <new_server> dbname
or can it be used as-is by piping it?
pg_dump <options> -h <old server> dbname | pg_restore
Thanks!
Regards,
Oleg
