Dear Adrian, Currently I am using postgres 11 version and I want to upgrade postgres 13 and I am doing this activity , first we take pgbase_backup from from Postgres 11 and restore this backup on postgres 13 (new server). I am not using pg_dump . I have done this activity on test server and its is working fine . My confusion is it is possible to in future we face any issue like upgrade and vacume or we can`t use all added new feature in postgres 13.

When doing this you should use the later version(13) of pg_dump to dump the earlier version, are you doing that? If you are then you have eliminated one possible issue. You should also read the Release Notes section of version 12 and 13: https://www.postgresql.org/docs/12/release.html https://www.postgresql.org/docs/13/release.html to see what things have changed that may affect your current set up. > > > > Regards, > Ram Pratap. > > -----Original Message----- > From: David Rowley [mailto:dgrowleyml@xxxxxxxxx] > Sent: 03 June 2021 18:01 > To: Ram Pratap Maurya; PostgreSQL mailing lists > Subject: Re: BUG #17046: Upgrade postgres 11 to 13 version > > On Fri, 4 Jun 2021 at 00:22, PG Bug reporting form <noreply@xxxxxxxxxxxxxx> wrote: >> i am creating new server and installed postgres -13 and take >> PG_BACKUP form current PRD server (PG version 11) and restore DB on >> PG-13 server. can you suggest if we doing upgrade by this activity there is any issue. > > The form you've used is for reporting bugs yet, this does not seem to be a bug report. > > If you're looking for general help and advice then you should consider asking on one of the mailing lists. > > https://www.postgresql.org/list/ > > pgsql-general might be the best fit. > > David > -- Adrian Klaver adrian.klaver@xxxxxxxxxxx
