no better idea... but i don't think is really an issue: in all active
branches hash indexes are not recommended (at least the docs says
there is no evidence that they will perform better than a btree and
establish that they are not crash-safe) so, if really there are some
in use and in an interval column (a very low combination i think) they
should be used to execute REINDEX anyway
