1. In case of registration of event source, either user has to pass the name or it uses hard coded default value, so
ifwe use version number along with 'PostgreSQL', it can be consistent. I don't see any way pgevent.c can know port
numberto 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
aproblem, as the event source name used will be different than what the name used during registration of event
source.
