Still, the app can reconnect. (So can psql.)
So...
1. How can I prevent (or redirect, or timeout, or anything) new
connections? I think superuser roles might be exempt from connection
limits and privileges. I could repeatedly terminate backends until
I'm able to rename the database, but... ick.
2. What's a better way to slave to a master database without being a
read-only slave? In other words, we want to use the production
database as a starting point each morning, but we'll be creating test
rows and tables that we wouldn't want to propagate to production. Can
I do this while the database is live through some existing replication
tool? The production database is on Ubuntu but the workstations are
Macs, FWIW.

More along the lines of what Greg has said. Not clear to me why an
individual dev box needs to be that current data-wise. Of course
stopping and starting your app should be easy, especially for the
developers so maybe that's a better place to start. Then dev can do it
when and how often suits dev best (even cronning shutdown app; reload
db; to happen 3am Sundays)
