I keep wondering if there's a role for GPUs in Postgres and haven't
figure out how to integrate them yet but the day when we'll be

Is this somewhere OpenCL is an option?

There is a talk about PgOpenCL upcoming -

Maybe I've sent this link earlier, but the VLDB 2008 paper Parallelizing Query Optimization (http://www.vldb.org/pvldb/1/1453882.pdf) might be interesting: not much IO between CPU and GPU. (hmm how much catalog access is necessary for cost estimization)). I suspect the biggest challenge is rewriting essential parts into a SIMD algorithm.
