Right, and the reason why the index is inconsistent with its table is
probably due to the ill-fated OS update you mentioned; if that was
in-place and unless you REINDEXed all the text-column-based indexes,
this might have lead to index corruption, so REINDEX your database after
you upgraded to the latest minor release of version 13.
