[2nd posting, as 1st never reached list due to non-membership.  Now a 
member, so hoping it will post quickly. Apologies in advance for 
duplication if 1st post ever makes it.]

NOTE:  This is a long message, however most are screen copy/pastes which
can be skimmed over.  I have taken great pains to document the steps
clearly, so as to prevent confusion.  If I have left out anything,
please advise.  Unless otherwise noted, commands are done running as a
user who is a member of the NT Administrators group.  (I have removed
1st line of BASH shell prompt for easier reading.)

For the past few weeks, I have been trying to get PostgreSQL 7.3.2
installed as an NT service using the usual methods.  Please note I have
done this in the past, under Windows 2000, using various versions of
PostgreSQL (7.1 and 7.2.1 come to mind), so I am familiar with the
steps.  Unfortunately, now I am running into difficulty, and after
having read this newsgroup, as well the usual Google searches, I have
come to the gut conclusion that the latest release revs of Cygwin appear
to have some kind of permission issue, possibly related to what I've
read about 'ntsec' being turned on by default in recent versions.
Unfortunately, I cannot track down the culprit.  So I am asking for any
and all help in determining what various file/directory permissions need
to be.

Please note this problem has occurred on multiple PCs now, both running
Windows 2000 and Windows XP Pro.  The following was my last attempt,
documented step-for-step, so you can see what I have done.

HARDWARE:
	Windows XP Professional SP1
	   with all updates thru today (29Apr2003)
	Intel PIII 866MHz CPU
	512MB SDRAM
	20GB HD (approx. 5GB free) / one NTFS partition (C:)

* Completely removed Cygwin from PC:
	* Removed C:\cygwin directory tree
	* Removed 'HKLM\Software\Cygnus Solutions' Registry key
	* Removed 'HKCU\Software\Cygnus Solutions' Registry key
	* Removed CYGWIN environment variable (and rebooted)
	* Left NT user 'postgres' (member of 'Users' group only)
	* Left Local Security Policy setting that allowed
	  NT user 'postgres' to 'Log on as a service'
	* Left PATH environment variable listing 'C:\cygwin\bin'
	  Beginning of PATH looks as follows:
	"C:\Perl\bin\;C:\WINDOWS\system32;C:\WINDOWS;C:\Cygwin\bin;..."

	  NOTE:  ActiveState ActivePerl v5.8.0.806 is located in
	         c:\Perl, in case it matters.

I have a local server mirroring a Cygwin mirror site (RCN), so my
install is done via a Windows share that is mapped to a drive letter
(i.e., install from local directory).

CYGWIN VERSION INFO:
	Cygwin setup.exe v2.340.2.5
	Cygwin           v1.3.22-1
	CygIPC           v1.13.2-1
	PostgreSQL       v7.3.2 (as packaged in Cygwin distribution)

* Logged in as user with Administrative Rights.
* Ran cygwin setup.exe, disabled virus scanner (McAfee), installed from
   local directory, and did a FULL install (EVERYTHING) vs. the default.
   Didn't want issues of missing packages, etc., and I've got the HD
   space.

* Once installed, ran BASH shell and did following (to show
   permissions):

* Using the document: /usr/doc/cygwin/postgresql-7.3.2.README

   Followed the steps for NT service as indicated under section headed
   with "The following is the NT services Cygwin PostgreSQL
   installation procedure"

1. $ ipc-daemon --install-as-service
    [Copy/pasted...worked fine]

	NOTE:  Double-checked, and NT service "Cygwin IPC Daemon" is set
	       to 'Automatic' and will Log On As 'Local System'.

2. NT user 'postgres' already existed prior to Cygwin install, so I
    assume this was not necessary.  Looking in /etc/passwd, I see the
    account listed.

	NOTE:  Interesting observation.  I notice if you do a
	       'mkpasswd -g' and just look at the output on the screen,
	       the format shown does NOT match what is in the /etc/group
	       file.  Specifically, the GUID indicated by mkpasswd is
	       what you'd expect in Unix, but the /etc/group file shows
	       NT SUID-RIDs. I ran into this when I tried making changes
	       at one point (prior to ripping Cygwin completely off box,
	       so should not affect this here), and the result was that
	       directory listings showed goofed up group settings.
	       Not sure if this plays into the new default behavior of
	       'ntsec' being turned on.

3.  Already done, but to make sure, I removed and re-added user 'postgres'.

4.  $ cygrunsrv --install postmaster --path /usr/bin/postmaster --args
"-D /usr/share/postgresql/data -i" --dep ipc-daemon --termsig INT --user
postgres --shutdown
     [Copy/pasted from instructions into BASH shell, and worked fine.]

	NOTE:  Double-checked, and NT service 'postmaster' is set to
	       'Automatic' and will Log On As '.\postgres'

5.  $ mkdir /usr/share/postgresql/data
     [Copy/pasted...worked fine.]

6.  $ chown postgres /usr/share/postgresql/data
     [Copy/pasted...worked fine.]

7.  [Copy/pasted...worked fine...got the following:]
     __________________________________________________________________

     $ net start ipc-daemon
     The Cygwin IPC Daemon service is starting.
     The Cygwin IPC Daemon service was started successfully.
     __________________________________________________________________

8.  [To do this step, I closed the BASH shell (to be safe), did a
     Log Off/Switch User, logged in as user 'postgres', ran the
     commands, and copy/pasted the following to a file:
___________________________________________________________________

"postgres".

______________________________________________________________________

______________________________________________________________________

* TADA!  As the NT Administrator used to install Cygwin, this works.

* Having read in various posts that permissions appear to be mangled,
   not only with /tmp, but also with /usr/bin, I decided to take a
   look (only showing portion, but rest looks the same):

* As seen above, /usr/bin/ is set so only the owner and group have
   execute permission.  As Jason Tishler has noted several times, one
   possibility is setting execute permissions for all.  So I did this:

* Since I did a chmod on /tmp, the CygIPC files (Multi*) show read/write
   permissions for all.  That's good.

* So, with /usr/bin permissions adjusted, let's try again.  And to be
   sure, let's also change group ownership:

$ chown postgres:Users /usr/share/postgresql/data

* Next let's stop cygipc, delete the tmp files, then restart, just to
   make sure:
______________________________________________________________________
$ net stop ipc-daemon
The Cygwin IPC Daemon service is stopping.
The Cygwin IPC Daemon service was stopped successfully.

$ rm /tmp/MultiFile*
$ net start ipc-daemon
The Cygwin IPC Daemon service is starting.
The Cygwin IPC Daemon service was started successfully.
______________________________________________________________________

* Finally, let's switch back to 'postgres' account, look at the cygipc
   tmp files (just to see what permissions we see from 'postgres' acct,
   and then let's try again:
______________________________________________________________________
postgres(at)SEESINK ~

   see in /usr/share/postgresql:

FINAL COMMENTS:

The issue definitely appears to be permissions-related, as I was easily
able to execute 'initdb' from the NT administrator account.  But what am
I missing?

Please note I have also tried changing the 'Cygwin IPC Daemon' service
permissions to make the service run in the same 'postgres' user context
if that were the case (doing the usual deleting of the /tmp/Multi* files
of course prior to launching), but to no avail.  Doing so showed the
/tmp/Multi* files as follows:
______________________________________________________________________
$ cd /tmp
$ ls -al
total 4046
drwxrwxrwx+   3 Frank    Users           0 Apr 29 13:36 .
drwxrwx---+  10 Frank    Users           0 Apr 29 11:06 ..
drwxrwxrwx+   3 Frank    None            0 Apr 29 11:40 CygIPC
-rw-rw-rw-    1 postgres None      3916520 Apr 29 13:36 MultiFileMsg
-rw-rw-rw-    1 postgres None        22032 Apr 29 13:36 MultiFileSem
-rw-rw-rw-    1 postgres None       202768 Apr 29 13:36 MultiFileShm
______________________________________________________________________

And no matter what, the following test was always the same when run from
the 'postgres' user account:
______________________________________________________________________
$ ipctest s
Test v0.03
Unable to create semaphore
semget : Function not implemented
______________________________________________________________________


If this isn't detailed enough, please let me know what other information
might be of use.

Thanks in advance for any and all help in this regard.  I've been
scratching my head on this one for awhile.  I have searched all over
looking for answers before posting here, but if I've overlooked
something trivial...well, apologies in advance.
