Installing PostgreSQL on NT:
---------------------------------------------------------------------------
It can be done by done by typing configure, make and make install.
1. Install the Cygwin package
2. Update to EGCS 1.1.2
(This may be optional.)
---------------------------------------------------------------------------
OPTIONAL
1. Install the Andy Piper Tools (http://www.xemacs.freeserve.co.uk/)
(This may be optional.)
You need at least the crypt library (also available as
ftp://sourceware.cygnus.com/pub/cygwin/xfree/libcrypt-cygwin-b20.1.tar.bz2)
---------------------------------------------------------------------------
CYGWIN32 INSTALLATION
1. Download the Cygwin32 IPC Package by Ludovic LANGE
http://penguin.cz/~horak/cygwin32_ipc-1.03.tar.gz
2. Untar the package and follow the readme instructions.
3. Apply the patch at the end of this file to the cygipc sources
before compiling the library.
4. I tested 1.03.
5. I used the \cygwin-b20\h-i568-cygwin32\i586-cygwin32\lib and
\cygwin-b20\h-i568-cygwin32\i586-cygwin32\include\sys instead of the
/usr/local/lib and usr/local/include/sys.
NOTE:
Also, the cygnus-bindir has to be placed in the path before the
NT-directories, because the sort.exe has to be taken for cygnus, not
NT.
---------------------------------------------------------------------------
POSTGRESQL INSTALL WITH NT SPECIFICS
1. Download the current version of PostgreSQL.
2. Untar the package.
3. Copy the files from \pgsql\src\win32 according to the readme file.
4. Edit \pgsql\src\template\cygwin32 if needed (I had to adjust the YFLAGS
path).
5. ./configure
6. make
7. create the directory /usr/local/pgsql manually: the mkdir cannot create a
directory 2 levels deep in one step.
8. make install
9. cd /usr/lical/pgsql/doc
10. make install
11. Set the environmental data
12. Initdb --username=jkr (do not run this command as administrator)
13. Open a new Cygwin command prompt
14. Start "ipc-deamon&" (background proces)
15. Start "postmaster -i 2>&1 > /tmp/postgres.log &" (background proces)
16. Start "tail -f /tmp/postgres.log" to see the messages
17. cd /usr/src/pgsql/src/test/regress
18. make all runtest
All test should be run.
NOTE:
By default, PostgreSQL clients like psql communicate using unix domain
sockets, which don't work on NT. 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.

PS: If you still have problems you can mail to Dan Horak <dan.horak@email.cz>
who is the maintainer for the win32 port
