I mean the old version and new version would need to take up disk space on the server.
Thus roughly doubled the disk space used.
And I'm telling you that pg_upgrade does NOT require that. It has a mode which allows an in-place upgrade (using hard links) that only requires a bit of extra disk space- certainly no where near double on a database of any size.
Thanks,
Stephen
