I looked into this and it seems like an innovative plan technically, but
most servers running PostgreSQL don't have a GPU. So it makes it more a
personal computer opportunity rather than a business server one, no?

Plus I wouldn't look at it ahead of a debugger being available.

If you wrote a CUDA function to perform a useful operation that might be
a good starting place to general understanding of how we might use this
in the future. PostgreSQL is extensible, so an add-in function might be
a useful module on pgfoundry. 

Maybe we could build in a hook to allow an external-function library to
provide sort capability... but I don't think anyone is going to take it
seriously for database core without a greater than normal amount of test
results and prototypes.
