I solved this, but it's still weird. I uninstalled again, this time deleting the windows user account that PostgreSQL created. So when I reinstalled everything was ok. Now I've realised that PostgreSQL is being very stupid about not allowing logins via psql from a windows administrator account. So I'm just running it as the guest user. But I still don't understand why psql works when run in a windows administrator account, but stops working as such when I add another user. This has me really baffled. Can someone please enlighten me (and the rest of us)? - Steve Quoting Steve Taylor <tayl0270@xxxxxxxxxxxxxxx>: > Hi. > > I installed PostgreSQL 8.1.2 on Windows XP Pro.
