Needing a database with a little more flexibility than MySQL, I decided to give PostgreSQL Server a try. While installing the latest version on Windows 7 (64 bit), I ran into an issue where the installer would freeze after entering the port to use. Originally I thought my download was corrupt, so I downloaded it again and tried an older version, but all of them would quit right after asking for the port.
I still don't know exactly why the freeze happened, but upon restarting my computer, the installer completed successfully. My guess is that something I had uninstalled earlier in the day causing something in the system to need a reset.
Yes, another one of those, "Restart your computer" fixes, but it worked.
