Right.

What it ought to be is the comment (if any) attached to the index's
column. Up through 8.4 this worked as expected, but in 9.0 and up
somebody seems to have disallowed comments on index columns. Not
sure how carefully that was thought through.

Again, the ability to stick comments on columns of those relkinds
seems to have been shut off as of 9.0. In 8.4 all of these description
columns are functional.
