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.
