If it is about incoming CONNECTION it may be firewall/antivirus
related ( I do not own a Mac and do not know whether they have this
kind of things like the recents windows have, I  just use Linux and
BSDs ).

If it says connection AND you are not expecting INCOMING connections
when it appear, something may be scanning your machine, or trying t do
it.

It does not seem postgres related, and certainly not a postgres bug.
It seems more like a mac related problem. The fact it started
appearing after an upgrade of the OS also points there. If I where in
your situation I would check whether the upgraded added some new
firewalling/connection control functionality.

In fact, your assertion that the problem still persist after you
uninstalled postgres certainly makes the not postgres related more
plausible. Bear in mind that your Mac may say postgres for other
reasons. I.e, my machine has this entries:

postgresql    5432/tcp            # POSTGRES
postgresql    5432/udp

in the services files ( which is used to translate port numbers to
service names, like

http        80/tcp        www www-http    # World Wide Web HTTP
https        443/tcp                # MCom

So any non numeric traffic dump of packets using port 5432 gets
labelled as postgres, even if postgres is not installed.
