Strange. Evidently it's getting as far as opening the connection
(pq_recvbuf is used in the backend, not the postmaster), but then
crashing after that. I can't see any reason why it would work for
pgaccess but not for you. (I notice that pgaccess uses the conninfo
style of arguments to pg_connect, but that shouldn't make a
difference...)

Can you provide a stack backtrace from the core file?
