doc: Note that CREATE MATERIALIZED VIEW restricts search_path.

nathan-bossart · nathan-bossart · commit d8ebcac547d7 · 2024-09-27T16:21:21.000-05:00
Since v17, CREATE MATERIALIZED VIEW has set search_path to "pg_catalog, pg_temp" while running the query. The docs for the other commands that restrict search_path mention it, but the page for CREATE MATERIALIZED VIEW does not. Fix that. Oversight in commit 4b74ebf.
