backup database problem

[jethro87]

When trying to backup my postgresql db on my laptop, I get the problem where in the config file I have to change the field from md5 to 'trust'. I can do this, but the file won't save at all. It says. "Cannot create the C:\program files\postgresq8.2\data\pg_hba.conf file. Make sure that the path and file name are correct. I tried saving the file somewhere else but it doesn't work.

Are you using Vista? If so, you have to open the file using 'run as administrator'. From the Start menu select

All Programs > PostgreSQL > Configuration Files and then right-click on "Edit pg_hba.conf" and select 'run as administrator' from the menu.
Then make the changes to the file and save it.
