* The general idea is the following: A target list consists of a list of
* Resdom nodes & expression pairs. Each Resdom node has an attribute
- * called 'resjunk'. If the value of this attribute is 1 then the
+ * called 'resjunk'. If the value of this attribute is true then the
* corresponding attribute is a "junk" attribute.
*
* When we initialize a plan we call 'ExecInitJunkFilter' to create

* to change the 'resno's...
