1. In case of registration of event source, either user has to pass the name
    or it uses hard coded default value, so if we use version number along with
    'PostgreSQL', it can be consistent.
    I don't see any way pgevent.c can know port number to append it to default
    value, am I missing something here?
2. In pg_ctl if we use port number, then if user changes it across multiple
    server restarts, then it can also create a problem, as the event source
    name used will be different than what the name used during registration
    of event source.
