'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!
