I would guess that the column type altering code is just short hand
for creating a new column of the correct type, copying the old column
into the new one, deleting the old column, and renaming the new column
to be the same as the old one.
That is just a guess though! But if it's all bundled inside a
transaction it should have about the same semantics, shouldn't it?
