The PostgreSQL project reports:

CVE-2018-16850: SQL injection in pg_upgrade and pg_dump, via CREATE TRIGGER ... REFERENCING.

Using a purpose-crafted trigger definition, an attacker can run arbitrary SQL statements with superuser privileges when a superuser runs pg_upgrade on the database or during a pg_dump dump/restore cycle. This attack requires a CREATE privilege on some non-temporary schema or a TRIGGER privilege on a table. This is exploitable in the default PostgreSQL configuration, where all users have CREATE privilege on public schema.
