I forgot to report this a few months ago: I had a very intensive COPY load, and this patch helped. The context was a server that was CPU bound on loading data (8 COPY on the same table in parallel, not indexed). This patch gave me a 10% boost in load time. I don't have the figures right now, but I could try to do this test again if this can help. At that time, I just tried it out of curiosity, but the load time was sufficient without it, so I didn't spend more time on it. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
