psql -H server_name -U username -W -c "\COPY (SELECT * FROM mytable) TO STDOUT" > mytable.csv

@echo off

    for /f "tokens=1-3 delims=/ " %%i in ("%date%") do (

      set day=%%i

      set month=%%j

      set year=%%k

     )

    set datestr=%day%-%month%-%year%

    echo datestr is %datestr%

    set BACKUP_FILE=D:\Documentos\Escaneados\Informe_medico_infarto_2019\Tension\Backup_BD\tension_%datestr%.backup

    SET PGPASSWORD=pasword

    echo on

    D:\BBDD\PostgreSQL\Instalacion\bin\pg_dump.exe -U postgres -h localhost -p 5432 tension_bd > %BACKUP_FILE%

    SET PGPASSWORD=

@echo off

    SET BACKUP_FILE=D:\Documentos\Escaneados\Informe_medico_infarto_2019\Tension\Backup_BD\prueba.csv
