Seems you can't do this:
create index on someschema.sometable ((modified_at::date));
If modified_at is a timestamp with a time zone:
ERROR: functions in index expression must be marked IMMUTABLE
But you can if it's a timestamp without a time zone. Anyway, any way of casting that as to use it as an index?
