Er, it is perfectly possible for two postmasters to use the same unix
socket path, abstract or not, as long as they listen to different
ports (all nodes in a single TAP test do that for example). So we
should keep a reference to the port used in the log message, no?

Dropping the hint for the abstract case sounds fine to me.
