Having two function complicates, a bit, interface between applicaation
and the database. But, then again, If I split it in two functions, then
one with the UPDATE still can't find temp table referenced in other
function, right?

I have no problem writing func1() example in plpgsql, it just seemed to
me that using sql instead of plpgsql (when I actually can use sql) gives
me a little performance improvement.
