What showed up in the postmaster log when this happened? I would like
*exact* error message texts, not approximations.

What happened when you tried to connect with psql? Again, exact, not
approximate.
It sounds like the postmaster got into a state where it was not
responding to SIGCHLD signals. We fixed one possible cause of that
between 7.1 and 7.2, but without a more concrete report I have no way to
know if you saw the same problem or a different one. I'd have expected
connection attempts to unwedge the postmaster in any case.
