It appears to be, more than anything else, some CUDA code wrapped in UDFs. Not sure I'd want that anywhere near my production stuff in that format.

This is false. PG has a well defined and modular query engine. pgstrom works by replacing and adding modules which allow for GPU support.

You're right, I got confused with another Postgres-GPU plugin type product.

However, Postgres isn't columnar. How does PG-Strom (now HeteroDB) arrange data for the GPU properly?
