We use pg_service.conf to hold the access credentials.
It's just pg_connect("service=sandbox") for example, where 'sandbox' is
the tag for the database you wish to access.
Using Debian it is kept in the /etc/php/7.3/apache2 path, where 7.3
represents the php version. It needs to be owned by the Apache user
which defaults to 'www-data'. Permissions are 0600.
