Found a bug:
create table foo as select x, floor(random()*100)::int as y,
floor(random()*100)::int as z from generate_series(1,1000000) f(x);
explain select count(y) filter (where y<0.01) from foo where x < 10000;
ERROR: variable not found in subplan target list
STATEMENT: select count(y) filter (where y<0.01) from foo where x < 10000;
Bisects to:
