Hm, so if this patch is applied now, and in 5 months or so somebody
implements pg_upgrade, this numeric storage patch would be rolled back?
OTOH, an upgrade mechanism that's compatible for future 8.3+ versions
only seems not too attractive.
A solution might be to keep the current numeric implementation under a
different name (deprecatednumeric or so), for backward compatibility
(this should apply to future storage format changes as well).
