1. Dropping Columns

   Thomas Swan <tswan@olemiss.edu> — 2000-08-21T23:32:13Z

   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.
