There is no timeout behavior in either libpq or the backend.  We have
recently seen a couple of trouble reports that seem to be due to
connections being dropped when they are idle for more than a timeout
period, but my guess is that that behavior is occurring in a firewall
or other network device between the client and server machines.

Recent versions of libpq allow a connect_timeout parameter in the
conninfo string passed to PQconnectdb(), as well as through the
PGCONNECT_TIMEOUT env var.
