PQsendQueryPrepared() is called after the conection's state has moved
to PGASYNC_IDLE so PQgetResult returns NULL. But actually there are
results. So, if pqPipelineProcessorQueue() doesn't move the async
state to PGASYNC_IDLE when queue is emtpy, uniqviol can run till the
end. But that change breaks almost all of other test items.
Finally, I found that the change in pqPipelineProcessorQueue() as
attached fixes the uniqviol failure and doesn't break other tests.
However, I don't understand what I did by the change for now... X(
It seems to me something's wrong in the PQ_PIPELINE_ABORTED mode..
regards.
