Hi
I'm sorting some columns like this: MyModel.order("LOWER(column) ASC")... But these queries are quite slow. I'm on Postgres by the way.
Does Rails support creating a lowercase index for these situations? I know Postgres has support for it and I guess I can create one like this (found on SO):
execute "CREATE UNIQUE INDEX index_products_on_lower_name ON products USING btree (lower(name));"Cheers,
Linus
