Yes, I did answer it: there is no such compilation option.
If you were willing to run a very nonstandard version of Postgres, you
could try widening t_hoff (see src/include/access/htup.h) but there is
nobody who can tell you what the fallout from that might be. One big
concern that I would have is the likelihood of O(N^2) behavior on very
long query targetlists.
On the whole I think you'd be a lot better off looking into hstore,
especially the improved 9.0 version.
