You aren't being very clear if you want to suspend a single backend or
the whole instance (which I'm not sure if feasible).
Individual backends will pause/continue via SIGSTOP SIGCONT.
I've done this under various interesting diagnostic conditions and did
not observe ill effects but there might certainly be some, especially if
you left the session paused for an extended period.
