C function returning rows, was Boolean text, with phrase ranking, search under Postgres

I too am interested in full text indexing under PostgreSQL.

Moreover, I have run into the same problem as you (in a different project
though): how do you return more than 1 value from a C function? I'd like to
return "rows", but, if at all possible, NOT to create a table. How about a
cursor? Perhaps one could then do something such as

insert into new_table select textsearch('bla...');

Does anyone know if it's possible?
