I tried this patch and noticed something weird. This is probably not
intentional:

explain analyze select * from generate_series(1,10) i where i>1 and
now()!=now();

Result  (cost=0.01..12.51 rows=333 width=4) (actual time=0.010..0.010
rows=0 loops=1)
  One-Time Filter: (now() <> now())
  ->  Function Scan on generate_series i  (cost=0.01..12.51 rows=333
width=4) (never executed)
        Filter: (i > 1)
        Rows Removed by Filter: -nan

Since it's never executed, nfiltered shows up as "-nan"
