Here's a patch which converts pmdammv to use Kens new "dynamic
namespace" interfaces.  It seems to function correctly when I
throw queries at it via dbpmda ... but no testing beyond that
has been done just yet.

Lemme know how it goes.  It also implements a DSO MMV, which I
also ran under dbpmda successfully.  Both these binaries should
no longer have the annoying-spurious-errors feature.

cheers.
