This new function is equivalent to PQpipelineSync(), except that it does not flush anything to the server except if the size threshold of the output buffer is reached; the user must subsequently call PQflush() instead. Its purpose is to reduce the system call overhead of pipeline mode, by giving to applications more control over the timing of the flushes when manipulating commands in pipeline mode.
