This looks mostly good to me but I think it would be better if we can
also add the information that the leftmost index column must be a
non-expression. So, how about: "Candidate indexes must be btree,
non-partial, and the leftmost index column must be a non-expression
and reference to a published table column (i.e. cannot consist of only
expressions)."?
