Someone at CMU has tried this, somewhat fruitfully.

This was based on GPUSort:

Unfortunately, the licensing of GPUSort is, if anything, more awful
than that for CUDA.

This would need to get pretty totally reimplemented to be useful with
PostgreSQL.  Happily, we actually have some evidence that the exercise
would be of some value.  Further, it looks to me like the
implementation that was done was done in a pretty naive way.
Something done more seriously would likely be radically better...
