> If a client issues something like:
> s = c.prepareStatement("");
> s.executeUpdate();
> The current logic will throw an exception on prepare.
> It's expected for the prepare to complete an an empty statement response to be returned from execute.
> This is the logic that is used by the PG JDBC driver for connection.isValid.
