Oh, wait ... I wonder if you saw that because you were running a new
backend without having re-initdb'd? Once you had re-initdb'd, then
of course there would be no old-format btree indexes anywhere. But
if you hadn't, then anyplace that was not prepared to cope with the
old header format would complain about pre-existing indexes.
In short, this sounds like a place that did not get the memo about
how to cope with un-upgraded indexes.
