Yeah, it's difficult. I don't think it can be done without the
generalized inner-indexscan stuff Tom was working on a few months
back, but I'm not sure what the status of that is at the moment.
For now, your best option is probably to write a PL/pgsql function
that iterates over table1 and then does a SELECT that calls func1()
and does whatever else for each row in table1. This can be a little
slow but I think it's the only option in existing releases of
PostgreSQL.
