Wow, @twdsilva. This is fantastic work! In terms of testing, we should test
this in the context of view index, salted tables, local indexes, immutable
indexes. Another dimension is the kind of expressions used in the functional
index. Let's figure out a good way to do this generally, so we get good test
coverage without too much copy/paste.

> 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.
