I'm trying to write an OpenCL function that would be executed inside PostgreSQL. To do this i create DLL from my OpenCL code and link it to postgres using User-Defined Function mechanism. Everything goes well until clGetPlatformIDs is called. Function returns error -1001, which I read that indicates problem with finding OpenCL drivers.

I've tried to compile the same code(i had to remove some postgres magic) to exe and runed it with success - all platforms were found correctly, so I assume that i have correctly set up SDK and drivers.

I am runing PostgreSQL 9.1 on windows 7 x64. I am also using Nvidia CUDA SDK 4.2 with Visual Studio 2010 and running my code on GeForce GTS 450.
