Thank you for your reply. My pg_ident.conf file is completely empty (well all commented out at least). Do you really need to map a Linux system user to a PostgreSQL role to get this to work? Seems like a bit of a hack to me. I'm probably missing something simple again. I don't need external access to the database at the moment, although it is helpful knowledge to have for the future.

This is all on my local machine so I've set pg_hba.conf to md5 for 127.0.0.1/32 which I assumed would just make it work.

Simon.
