Comandos copy para admonbd
Ni el doc toñito ni nosotros estabamos bien xD, este es el enlace de como se tiene que exportar a CSV desde pgadmin (checar desde paso 3)
PASO 3:
*****Execute SQL Query: Now enter the SQL query into the top left box of the Query window, select Query from the top navigation bar, and click Execute from the drop down as shown in the example image below.
https://www.question-defense.com/2010/10/15/how-to-export-from-pgadmin-export-pgadmin-data-to-csv
Estos son los comandos por terminal, los probe en linux y funcionan, agrego los normales (sin permisos, desde pgadmin es imposible acceder a un fichero, no se tiene acceso, segun lei en versiones recientes se puede)
otra seria cambiar los permisos CHMOD, pero como no tendremos tiempo preferible pegarlo en la carpeta del servidor.
PARA EXPORTAR A CSV (el primer enlace lo hace desde la GUI, solo lo dejo por si llega a suceder de que por X o Y razon no se pueda)
COPY datos TO '/var/lib/postgresql/9.1/main/datos2.csv' DELIMITER ',';
