They will retry, and this may fill your logs with error messages.

The scenario of "unreliable connections" is a bit different; in that
case, the trouble is that the slon considers the connection to be
"live" even though it isn't.  That causes problems.  If slon considers
a dead connection to be dead, there is no confusion :-).
