Post-Reboot Issue: Postmaster Not Accessible

After having to reboot my server/workstation this morning, I've a problem with
postgresql; one I've never before encountered.

The postmaster is running:

9959 pts/1 S 0:00 /usr/bin/postmaster -D /var/lib/pgsql/data

and the socket is present:

srwxrwxrwx 1 root root 0 2007-02-28 05:20 /tmp/.s.PGSQL.5432=

But I cannot connect to the database for SQL-Ledger nor from the command
line:

[rshepard(at)salmo ~]$ psql
psql: could not connect to server: Connection refused
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

The server is running locally. How can I test whether it's accepting
connections on the socket? And, what can I do to get it back to normal and
accpting connections?

Thanks,

Rich
