doesn't list which types can be indexed and which can't?
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;
