New to Postgre

I successfully installed Postgre 8.0 and was able to develop tables, columns and insert data.. However, after an uninstall Postgre would not let me proceeded reinstalling it.

Even after manually removing any vestige of Postgre the install still sees an existing account and refuses to proceed with the install.

There must be debris, from the first install, left on one or more of the registers.

The first event is a rejection of the name of the host computer. When I change the name on the Postgre interface it seems to become acceptable. It goes through the procedure of assigning an account and password but this is rejected by a message "the account already exists". Further changing the account names in the interface does not work.

Can someone direct me to the register that needs cleaning??
