Were you installing postgres manually?
Why? Didn't the "PT3 with postgres" installer work? This is the simplest way to install.
Are you using Vista?
Attn: Vista Users Installing PostgreSQL 8.3Did you have postgres installed previously? This can cause complications due to the postgres "user" already being set up.
If you are already using postgres for something else, you don't need to install it again.
If not, see these directions for starting again. Note: Try the PT3 with postres installer before doing the manual install of postgres, and see if that works.
