Installation on Windows Through Terminal Server

Hello,

I downloaded the 8.0 beta Windows installer at http://pgfoundry.org/projects/pginstaller.
It installed wihtout any issue on my W2K SP4 machine.

However, when trying to install it on a W2K server through a terminal server session, I have the following error:

==== initdb.log =============

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale french.

I have not checked the code yet, but I had very recently fixed a similar problem on the application my company develops (which is compatible with PotgreSQL ;-) ).
My guess is an issue with the identifier given to CreateFileMapping (which is usualy used to create a shared memory segment, to implement the equivalent of Unix's shmget) :
In short, if you want the segment created by a service to be visible from a terminal session, you must prepend "Global\" to it's name.
See http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/base/createfilemapping.asp for more information.
Beware, this is not supported under NT4, so you must have conditionnal code to prepend this only from W2K or up.
Also, there are similar issues with the name given to CreateMutex and OpenMutex (used to implement cross-process synchronisation objects).

Hope this helps
