I had PostgreSQL 8.3 running on a windows machine. The hard drive recently became unbootable, but the data is fine. We got a new machine and I'm re-installing Postgres. The new installer only has version 8.4 and a variety of 9.x releases.
Would I be able to install 8.4 and move the data over with no problems, or do I need to find the 8.3 installer. How about version 9? Is the migration as simple as moving the old "C:\Program Files\PostgreSQL\8.3\data" to the exact same place on the new directory.
