Subject: pgsql: Check for USAGE privilege on the subtype in CREATE TYPE AS RANGE
Date: Mon, 10 Aug 2026 13:41:25 +0000
Message-ID: <E1wtQFp-00000000y9w-2Ixa@gemulon.postgresql.org> (raw)
Check for USAGE privilege on the subtype in CREATE TYPE AS RANGE.
This omission allowed roles without USAGE on a type to create range
types that depend on it, which could prevent the owner from
changing the type later.
