It should be possible to access shared catalogs from an auth hook.
pg_stat_activity is neither shared nor a catalog.  Like Robert,
I find it astonishing that this works ever, because the info needed
simply isn't available until you've connected to a particular database.
The fact that the view is actually defined the same in every database
doesn't enter into that ...
