Ah, I had tried just a reindex xxx but not a reindex pg_class.

     * reindex_index will attempt to update the pg_class rows for the relation
     * and index.  If we are processing pg_class itself, we want to make sure
     * that the updates do not try to insert index entries into indexes we
     * have not processed yet.    (When we are trying to recover from corrupted
     * indexes, that could easily cause a crash.) We can accomplish this
     * because CatalogUpdateIndexes will use the relcache's index list to know
     * which indexes to update. We just force the index list to be only the
     * stuff we've processed.

Uhm. Is it possible we're mistakenly doing a HOT update because we're lying
about what indexes exist?
