For subscriptions using SERVER, changing the owner can change the effective connection string. However, ALTER SUBSCRIPTION ... OWNER TO did not validate the generated conninfo for the new owner. As a result, ownership could be transferred to a non-superuser whose generated connection string did not satisfy password_required=true. The ownership change succeeded, but the subscription would fail later when the worker or another command tried to connect. Fix this by making ALTER SUBSCRIPTION ... OWNER TO validate the new owner's generated conninfo with walrcv_check_conninfo(). Backpatch to v19, where SERVER subscriptions were introduced.
