How do I installing PostgreSQL on Windows NT or Windows 2000? ============================================================= $Date: 2000/10/18 21:14:56 $ 1. Install the Cygwin package. The Cygwin package provides a UNIX-like API on top of the Win32 API. It is available at . The 1.1.x series is recommended (1.1.4 was the latest at the time of this writing); using 1.0 or B20 might require extra efforts. For B20 you also need to download the separate crypt library at the same location. 2. Install the cygipc package, available at . Do not use versions prior to 1.04, they will not work. 3. Optional: The "Andy Piper Tools" at are a collection of pre-compiled libraries and utilities that you might find useful -- especially on Cygwin B20. 4. The Cygwin bin directory has to be placed in the path before the Windows program directories, because the sort.exe has to be taken from Cygwin, not Windows. 5. Start `ipc-daemon &' (background process) from the cygipc package. This program needs to be running anytime you start the PostgreSQL server (postmaster). 6. Proceed according to the INSTALL file. (./configure; make; etc.) NOTE: By default, PostgreSQL clients like psql communicate using Unix domain sockets, which do not work on Windows. Start the postmaster with -i, and when connecting to the database from a client, set the PGHOST environment variable to `localhost' or supply the hostname on the command line.
