There is -betterC [1] compiler flag that allows one to code 
without the D runtime and create programs that depend only on the 
C runtime, so there is no GC - and no GC related functionality 
also.

You probably want to try this route for creating the extension, 
as it will be simpler if you know C and the Postgres API.
