Hello. There are messages like this in shorewall's logs. x.x.x.x is
my site's IP address, both as the source and the destination. I've
been told that they're caused by postgresql. Having these messages
filtered out doesn't seem to affect postgresql in any way. Does
anyone know why postgresql would want to talk to itself in this way?
I'm using postgresql 7.4.7. My guess would be that this is some sort
of a heartbeat.
