This is the error message I'm getting by using: ''arg_id'' instead of: (CAST(arg_id AS integer)) SELECT production_scheduled_for_date('2005-05-12', '49'); ERROR: invalid input syntax for integer: "arg_id"
That's because ''arg_id'' is the string value "arg_id", those six characters rather than the value of any variable.
