BUG #2248: Fix for terminal server

The following bug has been logged online:

Bug reference:      2248
Logged by:          Fix for terminal server
Email address:      anthony.communier@laposte.net
PostgreSQL version: 8.1.2
Operating system:   Win 32
Description:        Fix for terminal server
Details:

I am sorry, these is not a bug report but i don't know where to post the
following message :

In order to fix problem with shared memory on the Win32 Terminal Server all
kernel object must be prefixed with Global\

Kernel Object are used by the following functions :

CreateEvent
CreateSemaphore
OpenSemaphore
CreateFileMapping
OpenFileMapping

I am not sure for Named Pipe

Those functions are used in the source directory src\backend\port\win32

I can't test these fix because I have no terminal server at home, but it
works fine with win32 services i have developped at work. So the following
lines can help you to solve the problem quickly :

Fix for version 8.1.2 :


sema.c:l 142
sprintf(semname, "Global\\PG_SEMSET.%d.", semKey);

shmem.c:l 92
sprintf(szShareMem, "Global\\PostgreSQL.%d", memKey);

I think that's all.

These problem should be encountered with fast user switch on Win XP but i am
not sure. Fast user switch is implemented like Terminal Server as far as i
know.

I hope it helps you.
