Actually, I think that your time would be better spent on the time
machine.  After all, with working time travel you wouldn't have to
worry about optimizing PostgreSQL.  Queries could take as long as they
needed to take and then you could send the response back in time to
right before the query was issued.

It's too bad you don't have the time machine finished already.  You
could use the time machine to go back in time and work on the time
machine :).  You'd be finished in no time.
