This means the client application is dropping the connection unexpectedly.
You have to find the application and fix it - a good log_line_prefix may
be a good way to find the application (e.g. "%t %u(at)%d %r" or something
like that).
Not too long ago I've received a lot of these when the apache http server
went crazy after an update and was dropping the connections (opened by a
PHP application) for some reason.
regards
Tomas

Or that OP has a networking issue. Some firewalls are known for
dropping what they think are idle connections when they aren't.

I don't think so.. EOF is an explicit termination, not a timeout as would
caused by a firewall dropping traffic. It's more like what happens when the
remote process on the client is killed for example. Postgres probably
expects to see some kind of "quit" command prior to receiving the EOF.

Well, this is exactly the error I used to get when the problem was
having a firewall timeout between client and server at my last job.
The fix there was to play with the tcp_keepalive settings

Npgsql is a very potent EOF-Generator if the client app doesn't properly
close (or dispose explicitly) connections.
