Hmm. I don't see any easy way out of that at the moment ... the
launcher would have to become a pseudo-backend, at least to the point
where it is able to read pg_database. I don't see how could workers
help the launcher with that, unless we made them write a flatfile
representation of pg_database, which would put us back where we started ...

I'll have a deeper look around.
