Description: pg_class.relhasindex not updated by vacuum
Details:
We rely on this column to build a list of tables restricted to only those
that have indexes to be rebuilt with CONCURRENTLY however the column is not
updated as documentation says by the vacuum. After a successful
analyze/vacuum/analyze against the entire database ALL tables from pg_class
have the pg_class.relhasindex = true even if they don't have any indexes.
