So I started to modify the second paragraph to indicate that the client
would send data on PQflush/buffer full/PQpipelineSync, only to realize
that the first paragraph already explains this.  So I'm not sure if any
changes are needed.

Maybe your complaint is only based on disagreement about what does libpq
do regarding queueing commands; and as far as I can tell in quick
experimentation with libpq, it works as the docs state already.
