There are several D libraries that I would consider "native": 
derelict-pq, dpq, dpq2 and ddb. The latter perhaps has the 
distinction that it doesn't use libpq, but rather implements the 
Postgres FE/BE protocol. That's a bit *too* native for my taste. 
It means the library maintainer has to keep up with changes to 
the internal protocol, which although published, the Postgres 
group doesn't have to maintain compatibility from version to 
version. For example, they haven't dropped the PQsetdbLogin 
function even though the PQconnectdb and PQconnectdbParams 
functions are obviously preferred. OTOH, there used to be an 
AsciiRow message format in the protocol, that was dropped, 
unceremoniously (not even mentioned in the release notes).
