You also need to set DPKG_MAINTSCRIPT_NAME to "postinst" as this one
is used by dpkg-maintscript-helper.

Given that dpkg-maintscript-helper is also impacted and not only
dpkg-trigger, I think that — yes — it really make sense to set them.

It would even be nice to have a fixed version sooner rather than later.

I just merged 596369 into this one (where cron is affected due to its
usage of dpkg-maintscript-helper).

Cheers,
