Not useful - it's all in ntdll.dll.

Attached. With a little poking in the VS debugger, it would appear that
the address shown is in fact in ntdll.dll. It shows the following call
stack:

>    ntdll.dll!7c8396d0()
     [Frames below may be incorrect and/or missing, no symbols loaded
for ntdll.dll]
     psql.exe!0040a269()
     ntdll.dll!7c839620()
     psql.exe!00404532()
     psql.exe!00404983()
     ntdll.dll!7c82fb23()
     psql.exe!0040a269()
     psql.exe!0040a32b()
     psql.exe!004099d2()
     ntdll.dll!7c82f9dd()
     msvcrt.dll!77bbcef6()
     msvcrt.dll!77bcc077()
     psql.exe!004011e7()
     psql.exe!00401238()
     kernel32.dll!77e523cd()

If I'm reading it (and understanding) correctly, that suggests the
caller might be GetVariable().
