The point is the rewrite I want to do is `col = 'a'` or `col in ('a', 'b')`
into `col_distinct = ANY(['a'])` or `col_distinct = ANY(['a', 'b'])`
respectively (or maybe `exists (select * from col__distinct where col =
ANY(['a', 'b']) and stats.row_group_id = col__distinct .row_group_id)`, I'm
still playing around with real world data and plans to see what is best; point
is it's an arbitrarily complex expression that I want left alone). As per above
if I do that before PruningPredicate it won't preserve my transformation and
will instead convert it to `true`.
