You sure it doesn't say
Socket command type e unknown
? Because that's how it's spelled in tcop/postgres.c, and I don't see
any other messages like this.
This message is basically saying that the backend got an unexpected
start-of-message character from the frontend. Usually this happens
because the frontend and backend have gotten out of sync, and the most
common cause of that is a failed COPY IN operation. COPY IN has no
error-recovery ability worthy of the name :-(.
Does your app use COPY IN a lot? What shows up in the postmaster log
right before these messages?
