> Instead of only defining the set of columns from the data table that make up
> an index, you should be able to use expressions. For example:
> CREATE INDEX upper_last_name_idx ON person (UPPER(last_name))
> Then in queries that use UPPER(last_name), we can replace them with column
> references to the index table.
