Good point --- actually he could convert it back to the original subselect style, as long as he's using the correct operator: SELECT * FROM c WHERE ARRAY[col1] <@ ANY(SELECT col2 FROM c); The one-element-array trick seems a bit awkward though. I wonder why we don't have an "anyelement <@ anyarray" kind of operator... regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
