Postgres can handle a variety of indexes including indexing on
expressions, which is why I pointed you to that link.

To cut to the chase, in the above link at:

http://www.postgresql.org/docs/9.2/interactive/indexes-opclass.html

there is this:

SELECT am.amname AS index_method,
        opf.opfname AS opfamily_name,
        amop.amopopr::regoperator AS opfamily_operator
     FROM pg_am am, pg_opfamily opf, pg_amop amop
     WHERE opf.opfmethod = am.oid AND
           amop.amopfamily = opf.oid
     ORDER BY index_method, opfamily_name, opfamily_operator;
