Well, that's the position that the current code is taking.
However, Takahiro-san and Euler's position is that if you do this:
create table foo (f1 int) with (toast.fillfactor = 70);
alter table foo add column f2 text;
Then the toast table should have the fillfactor setting. Right now they
are lost.
If we agree that the options are OK to be lost, then there's nothing we
need to do (and that's my opinion). If we don't, then we need some
weird hack to make it work somehow. Personally I think that it needs a
lot more work than it warrants.
