It seems to do what you'd expect if you doINSERT INTO jefftest(num) select a from generate_series(1,10) as
foo(a);INSERTINTO jefftest(num) select a from generate_series(11,20) as foo(a);INSERT INTO jefftest(num) select a from
generate_series(21,30)as foo(a);
I tried a function that raises a notice and called it asselect f1(1), generate_series(1,10);
and got 11 notices so it looks like there's some kind of phantom involved.
