I guess all the postgresql at .service files declare a
PartOf=postgres.service and have [Install]WantedBy=postgres.service.

This way systemctl start/stop/restart/reload postgresql.service will
forward that to all instances.
A target would probably be more suited for that, but targets currently
have limitations (e.g. regarding forwarding reload) so this doesn't
work and one has to misuse such a nop service.
