It seems somewhat strange that the only things COPY can do with its
output stream of bytes is exactly two modes that are baked into
Postgres in the core. This allows carefully written UDFs to do
whatever they will with the stream of bytes, such as sending into a
waiting libpq connection.

The patch is derived from functionality in the Truviso
postgres-derived database product which is non-optional. This is
extruded from that.

With the possible exception of squashing together the test cases into
their implementing patches, I would say this is at least two patches.
One is to a contrib, the other to core PostgreSQL. It so happens the
core addition makes the contrib changes much more obviously useful.
