I don't think you need the real package there - postgresql-12-plr has
been removed a year ago, and the dependency is even wrong in the
released bullseye package. I'd just drop it and go with
postgresql-plr.

Afaict the "real package first" requirement is only there for
build-dependencies.

So far we have refrained from adding empty dependency packages to each
of the PG extension packages because there's already enough
micro-packages, and these extra packages don't even solve the problem
completely.
