PostgreSQL version: 8.2.6
Operating system: Vista
Description: Access denied
Details:
I tried installing Postgres 8.2.6, everything went fine but then all of a
sudden i got the message "Acces Denied Cannot create user 'postgres'".
Is there any way i can solve this or has this been fixed in another
version?
I have to use postgres for school so any way or another i have to make it
work.
