Thanks a lot for quick reply. In this case, If I move table space out of old data directory using symlink, then can I remove old data directory? -----Original Message----- From: Bruce Momjian [mailto:bruce@xxxxxxxxxx] Sent: Tuesday, November 24, 2015 4:41 PM To: Yogi Barot Cc: 'Albe Laurenz'; 'pgsql-admin@xxxxxxxxxxxxxx' Subject: Re: Postgresql 9.4 pg_upgrade issues On Tue, Nov 24, 2015 at 08:32:18PM +0000, Yogi Barot wrote: > Hi, > > I was able to manage upgrade testing with cluster which does not have plsh for now. > > But I have another problem.

Or I can delete it manually? If you delete the old data directory, you will delete the old _and_ _new_ cluster tablespaces. > 2) Deleting old data directory will effect any functionality of postgresql new cluster? Yep, you can bet on that. :-) > 3) Also Need some clarification on link mode, what if I upgrade from 9.5. to future release using pg_upgarde link mode will still work on same data directory? Yes, but I suggest you shut down your server and move those tablespaces out of the data directory, update the pg_tblspc symlinks, and then restart the server. -- Bruce Momjian <bruce@xxxxxxxxxx> http://momjian.us EnterpriseDB http://enterprisedb.com + As you are, so once was I.
