The PostgreSQL server will reject messages greater than ~1 GB anyway. However, worse than that is that a message that is larger than 4 GB could wrap the 32-bit integer message size and be interpreted by the server as multiple messages. This could allow a malicious client to inject arbitrary protocol messages. https://github.com/jackc/pgx/security/advisories/GHSA-mrww-27vc-gghv
