I'm not really holding my breath for that to happen, considering
it would involve fundamental breakage of the wire protocol.
(For example, extended query protocol assumes that Describe
Portal only needs to describe one result set.  There might be
more issues, but that one's bad enough.)

When and if we break all the things that would break, it'd be
time enough for incompatible changes in psql's behavior.
