pgsql: Document search_path security with untrusted dbowner or CREATERO - Mailing list pgsql-committers

Document search_path security with untrusted dbowner or CREATEROLE.

Commit 5770172cb0c9df9e6ce27c507b449557e5b45124 wrote, incorrectly, that
certain schema usage patterns are secure against CREATEROLE users and
database owners.  When an untrusted user is the database owner or holds
CREATEROLE privilege, a query is secure only if its session started with
SELECT pg_catalog.set_config('search_path', '', false) or equivalent.
Back-patch to 9.4 (all supported versions).
