Broken pipes

Recently I've been noticing a lot of odd errors in our postgres logs, that involves a great deal of broken pipes and pq_recvbuf entries. I only noticed this when tables were not being created and am not sure what exactly is going on.

this is just a small bit of what keeps popping up in my logs, and if someone could help explain whats going on would be greatly apreciated.
