Error on pg_dumpall

[Carol Walter <walterc(at)indiana(dot)edu>]

Greetings,

I'm having a problem that I hope you can help me with.  I am getting  
the following error when I try to run pg_dumpall.

postgres(at)machine1:~$ /usr/local/pgsql/bin/pg_dumpall
pg_dumpall: could not connect to database "template1": could not  
connect to server: No such file or directory
        Is the server running locally and accepting
        connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

If I run the command "psql template1", I can connect to template1  
just fine.  It looks like pg_dumpall may be looking for template1 in  
the wrong place.

This is a new installation of postgresql 8.3 on a Debian Linux  
machine.  All my other machines are Solaris 10 running PostgreSQL 8.2.

Thanks,

Carol Walter
