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?
