You'd want to transform that into something more like this:

CREATE INDEX t1_idx1 ON t1(name);
This whole thing will probably provide no significant gain if your

This is not a big deal obviously since I can "ORDER BY 1 DESC" here.
I'm just trying to simplify my code since SQL is generated at runtime.

even makes sense to create index, execute query and then drop the
index. Though this won't save you any space since index will still be
created on disk, if I'm not mistaken.
