8099ce6f4a Add missing comments to fkey.c. Also, change the terminology used for comments and names in fkey.c from "referenced/referencing" to "parent/child". This is arguably less correct, but is easier to follow.

6a2fe09387 Generalize the IS and IS NOT operators so that their right-hand side can be 
an arbitrary expression and not simple the constant NULL.  They work like
= and <> except that NULL values compare equal to one another an unequal to
everything else.
