Well, it's been a bit of a mess, unfortunately, and I can understand
people feeling aggrieved.
I think there is general agreement that we want to be able to do:
COPY (SELECT ... ) TO ...
When we have that it would not be unreasonable to have a special case
for views which would transparently rewrite
COPY VIEWNAME TO
as
COPY (SELECT * FROM VIEWNAME) TO
So we would not necessarily be adopting a feature we don't want in the
long run, from a user visibility angle.
The issue seems to be that in adopting the present patch we would be
incorporating some code we will essentially have to abandon when we get
the feature we all really want, and which we hope will be available for
8.3. On that basis I can certainly appreciate Tom's reluctance to adopt
the patch.
It's a close call. On balance I'd be inclined to accept the patch if it
reviews OK, even though we will throw the code away soon (we hope).
