<para>

The server flushes its output buffer automatically as a result of

<function>PQpipelineSync</function> being called, or

on any request when not in pipeline mode; this function is useful

to cause the server to flush its output buffer in pipeline mode

without establishing a synchronization point.

Note that the request is not itself flushed to the server automatically;

use <function>PQflush</function> if necessary.
