Save the changes.
Then go to the PostgreSQL Database Functions window and click the "Important: If you are prompted to enter a password..." link at the bottom of the window and make the changes to the pg_hba.conf file as detailed there.
Then restore one of your backup databases files. After the restore is done, go to the File > Maintain Database Names window, click the Add button, enter a new name, check the "Dflt" box, in the last field choose "Select existing PostgreSQL database" from the list and select the db you just restored. Click the OK button to save the changes then CLOSE AND REOPEN PT.
