The code is verified as working when pulled out of a UDF and put into a
normal C program.

A few points about your code:

Furthermore, finding next to no documentation about it online and deciding

Hi,
I'm moving from the mysql camp and quite liking things like functions

These kinds of queries are super fast in MySQL because
your function is also not compiled on default. but pgcrypto is at the
