This is my first time on the Dlang forum. I like the language
but my usecase is a bit different.
I want to write Postgresql extension in D. Currently
extension can be written in C or C linked languages. Has
anyone done this or can point me to some code.
Thanks
Did you read this: https://dlang.org/spec/interfaceToC.html ?

Yes, but it's not useful, in Postgesql extension C code needs
to call D, without GarbageCollection. I am able to do this in
RustLang but I am not sure how to in D, as it has a GC. Looking
for examples from the community.
Thanks
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.
