8.3 is the latest version of PostgreSQL. Open the Start > Setttings > Control Panel > Add or Remove Programs window and find PostgreSQL in the list there, it will tell you what version it is.
If you install a new version of PostgreSQL the only way to convert over to it is to enter the new settings on the PostgreSQL Settings window in PT, then backup your old PostgreSQL databases using the PostgreSQL Database Functions window and then use those backup files to restore into the newer PostgreSQL.
