Hi!
Is there a NAT firewall or something like it involved anywhere between the two machines? If so, the connection may time
outat some point in time, and neither server nor client would be notified that the connection is lost. An "ERROR: could
notsend data to client: Broken pipe" message indicates almost certainly some kind of connection problem, so it's not
reallya PostgreSQL issue, but more like a networking one.
Kind regards
