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.)

1. Install the Andy Piper Tools (http://www.xemacs.freeserve.co.uk/)
   (This may be optional.)

1. Download the Cygwin32 IPC Package by Ludovic LANGE 
   http://www.multione.capgemini.fr:80/tools/pack_ipc/current.tar.gz
2. Untar the package and follow the readme instructions.
2a. Apply the patch from src/win32/ipc.patch
3. I tested 1.03.
4. 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.

1. Download the current version of PostgreSQL.
2. Untar the package.
3. Copy the files from \pgsql\src\win32 according to the readme file.
3. Edit \pgsql\src\template\cygwin32 if needed (I had to adjust the YFLAGS
path).
4. ./configure
5. make
6. create the directory /usr/local/pgsql manually: the mkdir cannot create a
directory 2 levels deep in one step.
7. make install
8. cd /usr/lical/pgsql/doc
9. make install
10. Set the environmental data
11. Initdb --username=jkr (do not run this command as administrator)

12. Open a new Cygwin command prompt
13. Start "ipc-deamon&" (background proces)
14. Start "postmaster -i 2>&1 > /tmp/postgres.log &" (background proces)
15. Start "tail -f /tmp/postgres.log" to see the messages

16. cd /usr/src/pgsql/src/test/regress
17. make all runtest

All test should be run, allthought the latest snapshot I tested (18-4)
appears to have some problems with locking.

By default, PostgreSQL clients like psql communicate by default 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.

Also, the cygnus-bindir has to be placed in the path before the
NT-directories, because the sort.exe has to be take for cygnus, not
NT.

Yutaka Tanida [yutaka@marin.or.jp] and I have examined IPC
library.

We found that postmaster doesn't call exec() after fork() since v6.4.

The value of static/extern variables which cygipc library holds may
be different from their initial values when postmaster fork()s child
backend processes.

I made the following patch for cygipc library on trial.
This patch was effective for Yutaka's test case.

Regards.
