Auto execute psql commands via batch file

psql via command line does not have an option for password. To run a scheduled task using psql is pointless without full automation.

Warning postgres recommends against doing this, and instead use a password file.

I use this script to kick off the psql command in python. But you can execute psql straight from the batch file, just check the %ERRORLEVEL% batch variable from the calling method.

@echo off

REM scheduled task point to .bat files
REM besides we need to make sure we have system variables in place

REM export a password for use with the system (no quotes)
SET PGHOST=host
SET PGDATABASE=database
SET PGUSER=user
SET PGPASSWORD=user

REM execute psql by file, even though echo is off, errors will still show
psql -X --variable=ON_ERROR_STOP= -1 -w -f filename.sql
