Maybe, but that would have a lot of side-effects on pg_dump's API
and probably on some end-user scripts. I'd rather not.
I haven't looked at the details, but I'm really a bit surprised
by Jeff's assertion that CREATE INDEX destroys statistics on the
base table. That seems wrong from here, and maybe something we
could have it not do. (I do realize that it recalculates reltuples
and relpages, but so what? If it updates those, the results should
be perfectly accurate.)
