This is not pure binding, and it is not compiles with current std library without warnings and errors:

std.stdarg is deprecated.  You should import core.vararg instead.

I think it is need to create exact binding for libpq and separately create any other higher-level abstractions for Postgres or universal for any DB.
But maybe someone has already done it? So far my searches have not yielded results.

A pure binding is trivial, just make one yourself. All you have to do is copy/paste from the C header.

On those errors though, I forgot to update that folderr.

You can try re-downloading it now or use the github version
which is a little more up to date
