I will slightly change the behaviour of the PostgreSQL port when installing the server package. The database administrator username will be postgres, as recommended by the PostgreSQL developers. The uid under which the software is installed will not change.
The initial database that is created using initdb when the package is installed will now prompt for a password for the DBA user. Until now we simply trusted every user connecting from localhost. These changes are necessary to prevent users from inadvertently exposing their databases. - Marc Balmer
