Backup Postgresql with .bat in windows - postgresql

Question

I want to create a postgresql database backup with a .bat file on Windows
I tried with this code:
#echo off
for /f "tokens=1-4 delims=/ " %%i in ("%date%") do (
set dow=%%i
set month=%%j
set day=%%k
set year=%%l
)
set datestr=%month%_%day%_%year%
echo datestr is %datestr%
set BACKUP_FILE=odoo_%datestr%.backup
echo backup file name is %BACKUP_FILE%
SET PGPASSWORD=openpgpwd
echo on
bin\pg_dump -i -h localhost -p 5432 -U openpg -F c -b -v -f %BACKUP_FILE% formation
But I received nothing.
And with this code:
#echo off
SET PG_BIN="C:\Program Files\OpenERP 7.0-20150818\PostgreSQL\bin\pg_dump.exe"
SET PG_HOST=localhost
SET PG_PORT=5432
SET PG_DATABASE=formation
SET PG_USER=openpg
SET PG_PASSWORD=openpgpwd
SET PG_PATCH=D:\odoo
SET FECHAYHORA=%date:/=%-%time:-0,8%
SET FECHAYHORA=%FECHAYHORA::=-%
SET FECHAYHORA=%FECHAYHORA: =0%
SET PG_FILENAME=%PG_PATH%\%PG_DATABASE%-%FECHAYHORA%.sql
%PG_BIN% - i -h %PG_HOST% -p %PG_PORT% -U %PG_USER% %PG_DATABASE% > %PG_FILENAME%
I have the same problem.
I want to use it later in the Windows Task Scheduler.

I think this is the solution for all:
#echo Backup database %PG_PATH%%PG_FILENAME%
#echo off
SET PG_BIN="C:\Program Files\PostgreSQL\bin\pg_dump.exe"
SET PG_HOST=localhost
SET PG_PORT=5432
SET PG_DATABASE=motor_8
SET PG_USER=openpg
SET PG_PASSWORD=openpgpwd
SET PG_PATH=C:\OEM
SET FECHAYHORA=%date:/=%-%time:-0,8%
SET FECHAYHORA=%FECHAYHORA::=-%
SET FECHAYHORA=%FECHAYHORA: =0%
SET PG_FILENAME=%PG_PATH%\%PG_DATABASE%_%d%_%t%.sql
%PG_BIN% -h %PG_HOST% -p %PG_PORT% -U %PG_USER% %PG_DATABASE% > %PG_FILENAME%
#echo Backup Taken Complete %PG_PATH%%PG_FILENAME%

It is hardly surprising that your scripts don't work, because they contain typos all over. I don't claim that I found them all, but here is a list of those that I did spot:
First script:
There is no option -i for pg_dump.
Second script:
There is a bogus space in -i, but since that option doesn't exist and will cause an error, it should be removed.
You set PG_PATCH and reference PG_PATH.
The environment variable PG_PASSWORD is not recognized by libpq. Remove the underscore.
You can figure out all this if you read the error messages you undoubtedly get. You should also always include such error messages in questions like this.
