trouble with pg_dumpall

Hi Everybody,

I started running 8.3.0 recently on dell hardware
with redhat advanced server 4.

I have a problem with pg_dumpall via crontab.
I had a simple crontab to do the same thing on
8.2.4 and the same thing doesn't work.

Here's my very simple crontab entry:

xx xx * * * sh /usr/local/pgsql/cron_dir/moo.sh

and moo.sh is eqally simple:
#! /bin/bash

. .bashrc

filename=`date +%G%m%d.%w`.gz
/usr/local/pgsql/bin/pg_dumpall > $filename

Here's what I get back as output is:

Password:
pg_dumpall: could not connect to database "template1": fe_sendauth: no password supplied

This is not what happened on 8.2.4. I read 8.3.0 man
page on pg_dumpall. Here's what it told me:

The file .pgpass in a user's home directory or the file referenced
by PGPASSFILE can contain passwords to be used if the connection
requires a password (and no password has been specified otherwise).

I have .pgpass in /usr/local/pgsql and when I type
psql dbname
It lets me in without asking the password. So I don't
understand why I get what I get: fe_sendauth: no password supplied

I ran a different cron job which looks like:

#! /bin/bash

. .bashrc

echo PGUSER: $PGUSER
echo PGDATABASE: $PGDATABASE
echo PGHOST: $PGHOST
echo PGPASSFILE: $PGPASSFILE
echo PGDATA: $PGDATA

and everything it told me checks out with what I get from
interactive session.

Please tell me what I am doing wrong. I am at the
end of my wits.
