Safety
While pgx controls the types for which PgNode is implemented and only pgx can implement
PgNode it cannot control the members of those types and a user could assign any pointer
type member to something invalid that Postgres wouldn’t understand.
Because this function is used by impl Display we purposely don’t mark it unsafe. The
assumption here, which might be a bad one, is that only intentional misuse would actually
cause undefined behavior.
