I would suggest uninstalling PT3 and PostgeSQL using the Start > Settings > Control Panel > Add or Remove Programs window.
Then delete the remnants of the c:\program files\postgesql\8.3 folder.
Download this version of PostgreSQL:
http://wwwmaster.postgresql.org/downloa ... .3.1-1.zipExtract all the files out of the ZIP file into a separate folder.
Then double-click on the postgresql-8.3.msi file to install it.
The last part of the install is the Stack Builder application you can run. See here for what to select...
archives/PT2/viewtopic.php?t=24880Then on the PostgreSQL Settings window in PT2, you would select "PostgreSQL Unicode" from the list.
Later, you can reinstall PT3 but when you do, you just need to do the install that doesn't include PostgreSQL because it's already installed.
