Hi, I'm writing a set-returning function which places a file handle into PG's FuncCallContext's user_fctx space. My problem is that when the function is ran with a limit clause (SELECT * FROM foo() LIMIT 10) the server will stop calling the function automatically, not giving me a chance to close the file handle. Is there a way to get the limit value inside of foo() and set the max max_calls parameter correctly?
