I'm not sure that's a relevant precedent at all. What that number is
is the time that pg_ctl will wait around for the postmaster to start or
stop before reporting a problem --- and in either case, a significant
delay (multiple seconds) is not surprising, because of crash-recovery
work, shutdown checkpointing, etc. For pg_isready, you'd expect to get
a response more or less instantly, wouldn't you? Personally, I'd decide
that pg_isready is broken if it didn't give me an answer in a couple of
seconds, much less a minute.
What I had in mind was a default timeout of maybe 3 or 4 seconds...
