Thank you, Jeff.  That worked like a champ.  My initial problem
Had to do with not understanding the concept of OID datatypes.
My next learning task is to read up on OID.

Thanks again, Mark

It might be better on pgsql-sql, but I'm not sure.

You want to join on pg_class.oid.  You can see the info on pg_index here in
the docs: http://www.postgresql.org/docs/8.1/static/catalog-pg-index.html

select i.indexrelid,c.relname from pg_index i, pg_class c where i.indexrelid
=
c.oid;

will likely give you what you're after.
