[postgis-users] Tabla con diferencias (Table with differences)

[Néstor Ramires]

Hello
I have two tables with line geometry the table forestal_ln with their respective data and the table mineral_ln with their data.
How do I get a third table with the lines that are in the mineral_ln table and are not in the forestal_ln table?
Below I leave the data with which I am working.

Hola
Tengo dos tablas con geometría de lineas la tabla forestal_ln con sus respectivos datos y la tabla mineral_ln con sus datos.
¿Como puedo obtener una tercer tabla con las líneas que se encuentran en la tabla mineral_ln y no están en la tabla forestal_ln?
Abajo dejo los datos con los cuales estoy trabajando.
