I need to move my master postgresql deployment to a new server.
I am comfortable with stopping all connections then doing a pg_dumpall >
psql to move the databases, they are not huge so this completes in an
acceptable time and I am not expecting any data loss but I am unsure of
what impact this will have on the streaming replication. I will be
rebooting the new server with the old servers network configuration so I
am hoping that when I let connections back in, replication will just
restart but I cant find any documentation that says so.
Currently the slave serves as a read-only target for various services so
they should all just keep running.
The postgresql versions are 10.20 on the old and 10.17 on the new.
(Basically this is a CentOS7 to Rocky8 migration) I have been using the
PGDG rhel version so it is a little ahead of the appstream
Comments ?
