Summary		(es) pgx es un controlador y kit de herramientas de PostgreSQL para Go. Antes de la versión 5.9.2, puede ocurrir una inyección SQL cuando se utiliza el protocolo simple no predeterminado, se utiliza un literal de cadena entre comillas de dólar en la consulta SQL, ese literal de cadena contiene texto que sería interpretado como un marcador de posición fuera de un literal de cadena, y el valor de ese marcador de posición es controlable por el atacante. Este problema ha sido parcheado en la versión 5.9.2.
