Dropping Columns
How nasty would dropping columns be?
I've just now started going through the source and am trying to find where
it would fit in... if it could be done without a nightmare.
Any pointers?

Long discussion in February, and again in June in HACKERS. (Hmm, the
new User's Lounge seems to have gone in, but now we've no links to
mail archives. Ah, here's a bookmark I can use to get in.)
Here's one pointer:
http://www.postgresql.org/mhonarc/pgsql-hackers/2000-06/msg00324.html
The search feature on the front page will search the mailing lists for
you, it's just a bit slow.
Oh, look in <your pgsql source tree>/doc/TODO.detail/drop
Looks like the thread from HACKERS is in there.

For now you can get there from the general info page in the user's
lounge. I'm working up the search page now.

I have an solution which uses 2(logical/physical) attribute numbers.
However I'm not satisfied with it.
It isn't so clean as I expected.
It breaks backward compatibility ... etc.
