What platforms does PostgreSQL support?

In general, any modern Unix-compatible platform should be able to run PostgreSQL . The platforms that had received explicit testing at the time of release are listed in the installation instructions.

PostgreSQL also runs natively on Microsoft Windows NT-based operating systems like Win2000 SP4, WinXP, and Win2003. A prepackaged installer is available at http://pgfoundry.org/projects/pginstaller. MSDOS-based versions of Windows (Win95, Win98, WinMe) can run PostgreSQL using Cygwin.

There is also a Novell Netware 6 port at http://forge.novell.com, and an OS/2 (eComStation) version at http://hobbes.nmsu.edu/cgi-bin/h-search?sh=1&button=Search&key=postgreSQL &stype=all&sort=type&dir=%2F.
