Обсуждение: PostgreSQL related problem on iMac
Good morning Postgre, I have a small notification pane which appears randomly, in the same = position every time, towards the top of my iMac 27" (2009) screen in the = midline. It first occurred after the recent MacOS Sierra upgrade. The pane is on = screen for less than a second each time, sometimes it is very brief, and = is about whether to allow or deny Postgre to access incoming content (or = something of the sort!). There is no knowing when it will appear. I have = actually succeeded in clicking on it a couple of times but it still = comes back - randomly throughout every computer session. If I am typing = when it appears it can induce typing errors. 'Apple help=E2=80=99 did not know about this issue. They advised a scan = with malwarebytes but this did not help. I uninstalled Postgre from the iMac as I could not see that I would have = a use for it but that did not help either. I would very much like to be rid of this problem. With thanks, Neil Marshall=

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. > I uninstalled Postgre from the iMac as I could not see that I would have = a use for it but that did not help either. > I would very much like to be rid of this problem. 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.

This sounds suspiciously like the problems some of us saw a year or two back with "accept incoming network connections" prompts on machines that weren't actually configured to allow any incoming connections. The answer turned out to be that some OSX versions put fe80::1%lo0 localhost into /etc/hosts, which is wrong because it's not really a local address. So when the postmaster tried to bind to localhost, the firewall quite correctly saw that as an externally exposed address. In short, if you see a line like that in /etc/hosts, it's wrong and you should remove it. I'm not real sure why this problem would suddenly appear with Sierra though. It was current a couple years ago but I thought Apple had fixed it by now. Maybe your issue is something else, but I don't have enough info to speculate. regards, tom lane
