Each of those numbered sub-folders in \base is a different database (could be HM1, HM2, PT4, etc).
For reinstalling SQL to the same DB, follow these steps:
1) Uninstall PostgreSQL from the Windows Control Panel.
2) If you are moving the DB to a different drive/partition, manually cut or copy the \Postgresql\8.x\data directory to it's new location.
3) run the command - start > programs > accessories > command prompt > right-click > run as administrator
PHP Code:
net user postgres /delete
4) reboot.
5) Install the same version of PostgreSQL as your current DB using these instructions - http://faq.holdemmanager.com/questio...g+Old+Database

6) If you have moved/installed your DB to a non-default location, please make sure to change the 'Data Directory' path during the installation.
