So the answer is that ILIKE will not use indexes.
But using lower()/LIKE will give you exactly the same results. lower()
forces all column data to lower case for the purposes of comparison.

Yes, I know that already. I wasn't talking about LIKE; I was talking
about ILIKE. The data in the column is mixed-case.
You can use an index on an expression like "lower( col ) LIKE ... " as

I am pretty sure the answer is no, but ... is there any way to get
'ilike' to use an index? It seems like something that a lot of people
would want to do. Otherwise, should I just create redundant
