[ checks... ] No, it isn't. My recollection is that we looked very
hard at this around the time DROP COLUMN was implemented, and concluded
that we weren't ever going to support it, because distinguishing
physical from logical column numbers would create a nigh-inexhaustible
source of bugs. See the pghackers archives for lots of discussion.
