It's more or less intentional, per elog.c:
/*
* This flush is normally not necessary, since postgres.c will flush out
* waiting data when control returns to the main loop. But it seems best
* to leave it here, so that the client has some clue what happened if the

* flush won't hurt much ...
*/
pq_flush();
Perhaps it'd be sensible to do this only in debugging (ie Assert)
builds?
