This seems like it must be a server bug, and yet this log trace:

> LOG: incomplete message from client
> ERROR: invalid string enlargement request size 1476395004
> LOG: unexpected EOF on client connection
> LOG: incomplete message from client
> ERROR: invalid string enlargement request size 1476395004
> LOG: unexpected EOF on client connection

suggests that the client side is sending bogus data.

Can you provide a self-contained test case for this?
