Does the jdbc driver work with EmptyQueryResponse? At the protocol
level, if you send a Query message with an all-whitespace sql string,
the backend is supposed to reply with a single EmptyQueryResponse
message and then issue ReadyForQuery again. I have a feeling that jdbc
is probably "too smart" for this to work, but it could be worth a
shot.
