pg_dump fails on 7.4 Postgres

This may be my second posting but I think I've done it correctly this time.
At this point, I am unable to do a pg_dump using our new Rec Hat
Enterprise Linux AS 4 version of Postgres which is version 7.4.
Here's what I get when I try to do a pg_dump of our database:

---------------------------------------------------------------------------------------------------------------------------
[~]$
[ ~]$ /usr/bin/pg_dump dcf_20050404 >& /~/dcf_20050404_`date +%y%m%d`.dmp

Here's Postgres rpm on the machine in question:
