Re: $_SERVER['SERVER_ADDR'] ; returns wrong value "::1"

::1 is a function of the PHP $_SERVER[''] internal function, not a
PostgreSQL problem. It will display ::1 on any database, you program a
PHP custom function to call the whole IP address.  The real question is
that a problem in a production environment? Of note, outside IP
addresses will display fine using $_SERVER[''].

Good Luck,
