Also, this is documented as followins in
https://www.postgresql.org/docs/17/sql-createindex.html .

  While CREATE INDEX is running, the search_path is temporarily changed to pg_catalog, pg_temp.

By the way, this is not mentioned in CREATE MATERIALIZED VIEW documentation, although
we can find in REFRESH MATERIALIZED VIEW doc. So, I sent the doc patch in [1], 
and create a commitfest entry [2].
