I've been tackling this for a while. I setup a completely new machine. I've installed a fresh copy of postgresql and all my other dependencies. Basically, I get these database disconnections at random times. I can perform identical requests and either it works or it doesn't. Very nondeterministic in outward appearance. Watching logs at Postgresql, it doesn't even get a connection. Now, I would expect that if it never connected I would get this problem when establishing the connection and getting the cursor, but I get it when trying to actually use the connection later. Given the traceback below, I would expect to see a connection made in the pg logs, and then disconnected for some reason later. I don't, so I wonder if there is some clue in that mismatch.
