Dept of second thoughts: let's make sure that get_index_stats_hook is only
applied to expression indexes, not to plain relations. The original coding
in btcostestimate conflated the two cases, but it's not hard to use
get_relation_stats_hook instead when we're looking to the underlying relation.

Good catch, thanks.
