BTW, is this sort of added functionality to the ALTER TABLE/ALTER COLUMN in
the queue for an upcoming version of PG? I heard that there was some talk of
an ALTER TABLE <table> DROP COLUMN <col> in the hackers list a while ago. I
would also like to see an ALTER TABLE <table> ADD COLUMN <col> AFTER <col>.
I know it's not a production concern b/c I can simply use dump/restore but
I'm just interested if it's coming some day ;)
