No. Neither rsync nor streaming replication will do version upgrades.
The only ways to do version upgrade are:
1. pg_dump + pg_restore
2. pg_upgrade
3. Logical replication

Thanks Ron for your suggestion.So for pg upgrade in streaming replication setup, rsync will be a better option for standby upgrade if we are using --link option or recreating the standby, once upgrade completes on primary? Any suggestions on this please.Best Regards,RamanOn Mon, Nov 18, 2024, 22:41 Ron Johnson <ronljohnsonjr@xxxxxxxxx> wrote:On Mon, Nov 18, 2024 at 11:08 AM Motog Plus <mplus7535@xxxxxxxxx> wrote:--Dear Team,We are in the process of upgrading our PostgreSQL database from version 12 to version 15. I would greatly appreciate your advice on the following:1. Would it be recommended to use the --link option with the pg_upgrade command, from disk space point of view?Yes.Are there any potential downsides to consider?Very much: it's a one-way journey. No rolling back if something goes wrong!2. Do you have any suggestions or best practices for performing an efficient upgrade in a replication setup (streaming replication) for both the primary and standby servers?Streaming replication is not an upgrade method. Logical replication is absolutely a valid method of upgrading PG on one server to PG on a different server.Death to <Redacted>, and butter sauce.Don't boil me, I'm still alive.<Redacted> lobster!
