We generally don't like to change behavior of back branches without
ironclad agreement that the existing behavior is a bug ... which this
surely isn't. Also, the discussion leading up to that patch specifically
considered and rejected back-patching; so I'm disinclined to overrule
that decision now.

I would suggest that an every-three-second health check is not
appropriate, especially one that is so minimal that it only
detects whether the postmaster is alive.
