Hello,

For my undergraduate final year project, I want to study functional
programming and intraoperation parallelism in DBMS. Specifically, I am
going to investigate into whether FP could be useful for implementing
operations as selection, projection, and join (these operations could
easily be parallelized and FP's referential transparency could give some
benefits here).

I figured that Postgres is a good DBMS to study since it makes use of
intraoperation parallelism. However, Postgres is written in C. Is there a
way to achieve what I have in mind? Is it doable given how the code is
structured?

Regards,
