Even more to the point, see the first compatibility entry at [1]:

    * Change functions to use a safe search_path during maintenance
      operations (Jeff Davis)

      This prevents maintenance operations (ANALYZE, CLUSTER, CREATE
      INDEX, CREATE MATERIALIZED VIEW, REFRESH MATERIALIZED VIEW,
      REINDEX, or VACUUM) from performing unsafe access. Functions
      used by expression indexes and materialized views that need to
      reference non-default schemas must specify a search path during
      function creation.
