I would strongly suggest you do this instead:

   LOWER(colname) = LOWER('x')

This is far more bullet-proof than lower-casing in the client, in case
the client and the server differ (mismatched locales, etc.).  If you
don't want to use ILIKE for portability reasons (perfectly reasonable),
I suggest the analogous:

   LOWER(colname) LIKE LOWER('x%')
