Hi, The problem comes after pgsql is ¿succesfully? installed without error messages and all other procedures suggested on documentation are completed in the same form. At this point, with postmaster running, EVERYBODY can do: > pgsql -l, obtaining the list of databases > createuser > destroyuser > destroydb > createdb It surprises me because i have installed this version on a RedHat 6.1 ann it works whithout any special thing. What's the problem, if its a problem ? Bad instalation ? Is a bug ? Thanks.
