> Yes, I can run it.
I entered to the step definition window
c:\mydir\mysubdir\mybackup.bat
and ran pgagent.
1_1.bat file now remains and contains line
c:\mydir\mysubdir\mybackup.bat
I executed from cmd line
runas /user:mydomain\postgres cmd
cd "C:\Document and settings\ postgres\Local Settings\temp\pda48EB.tmp"
1_1.bat
and pg_dump.exe creates backup file
So running 1_1.bat manually as user postgres works OK.
