That would require the backend to buffer the entire query response, which isn't a great idea. I would expect that such an operation would need to interleave CopyData to the backend with DataRow responses. Such a thing could possibly be built on COPY_BOTH mode, but it would be a lot of work (at both ends) for extremely debatable value. The general idea of COPY is to load data as fast as possible, so weighing it down with processing options seems like a pretty dubious idea even if the implementation were easy.
That was my reaction. I would look it this very skeptically. cheers andrew -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
