 Running Postgresql 7.4.2 on Windows 2000 with Cygwin !

 Dear Sirs

 I have installed Cygwin on my computer (a K6-2 500Mhz
 with 256Mb RAM) and downloaded the file :

    cygipc-2.03-2.tar.bz2

 and installed the cygipc-daemon in the file.

 I have downloaded the file postgresql-7.4.2.tar.gz
 and unpacked it and run the following commands:

         ./configure
         make
         make install

 I have made a shell-script that contains the
 following lines:

    ipc-daemon2 &
    initdb -D /usr/local/pgsql/data
    postmaster -i -n -d 2 -D /usr/local/pgsql/data

 When I run this shell-script I get the following
 error-message from initdb :

  FATAL: could not create shared memory
         segment: Function not implemented
  DETAIL: Failed system call was
          shmget(key=1, size=1081344, 03600)
  initdb: failed

 What is wrong here ???????????
 How can I solve this problem ????????????

 I hope to hear from you.

 Best regards
