Well it'd be nice from a consistency point of view.  And it wouldn't be too
hard.  I don't think it's essential for 7.3, as it would be perfectly
backwards compatible.  I'll add it to my TODO list, right after changing
column type :)

Anyone have any ideas on how we could implement changing column type.  We'd
have to move all dependencies and any object that refers to the column by
its attnum,  etc...  I guess we could steal a lot of the renameatt() code...
