Is it possible to select index values ?
I haven't found any documentation that says "No", but I haven't found anything that says "Yes" either.
The reason - I have a few function indexes that are working as partial indexes. I'd like to run some analytics on them
(todetermine uniqueness of values, decide if i should change the function, etc). It would be easier if I could somehow
accessthe index contents than re-create the index data into a temporary table.
