'pgaccess' - Can't Connect to Backend

Configuration
-------------
  MkLinux
  postgresql-6.3.2
  pgaccess-{0.86,0.91,0.93}


Problem
-------
I can connect to the backend via 'psql' but not 'pgaccess'.
Both 'pgaccess' and 'postgreSQL' are running on the same machine.

Pgaccess gives the message:

    Error connecting database
    Connection to database failed
    connectDB() failed: Is the postmaster running
    and accepting TCP/IP (with -i) connections
    at 'localhost' on port '5432'?


Observations
------------
Here's the relevant process info (in particular, note the '-i'
option):

    /usr/bin/postmaster -i -S -D/var/lib/pgsql
    /usr/bin/postgres -p -Q -P5 -v 65536 collection

Also, the following 'netstat' output (corresponding to the 'psql'
connection) shows that port '5432' is, in fact, being used:

    Proto Recv-Q Send-Q Local Address           Foreign Address         State
    tcp        0      2 cs:3123                 localhost:5432          CLOSE


I've used 'pgaccess' successfully before, but I must have changed
something (permissions, etc.) during an OS upgrade.

Any help will be appreciated!
