"The Flush message does not cause any specific output to be generated,
but forces the backend to deliver any data pending in its output buffers.
A Flush must be sent after any extended-query command except Sync, if the
frontend wishes to examine the results of that command before issuing more
commands. Without Flush, messages returned by the backend will be combined
into the minimum possible number of packets to minimize network overhead."
