We will then need "build"-time requires (build-depends would say debian)
so that the system knows what's needed to run the install or upgrade
scripts.  I've been thinking that's for 9.2, but maybe that would be a
simpler fix for you here.

Oh and it needs to be able to define plpgsql as such a dependency, so it
will probably need to be an extension…
