pg_dump -> restore will break your streaming replication. You'll need to set it up again.
That's what I thought might be the case.
If the PG version isn't changing and you're still on the same version of Linux, rsync would be easier.
I did an ELevate upgrade on the slave from CentOS7 to Rocky8 and then just rename 10/data to data and that seemed to work just fine.
But upgrading that way takes too long for the master so I build a new server instead. So, if I shutdown both postgresql instances old and new, rsync the data directory and restart on the new. I should be OK ?
