I guess not, one way is to take an ascii schema-only dump and parse it,
looking for GIST indexes.

Anotherway is to look in those tables:
SELECT oid,* from pg_opclass ; -- to find the GIST class
SELECT c.relname,indclass from pg_catalog.pg_index i,pg_catalog.pg_class c where indexrelid=c.oid;
^^ to find those indexes which have this gist class oid in the indclass field.

Note tho, that indclass is oidvector, and i dont know how you could iterate on those (by SQL), 
without writing a C (or other) program.
