I've just tried to reproduce the problem here, but things just work
for me. What I did was to install postgresql-9.1 9.1.22-0+deb7u1,
start it on a de_DE.utf8 cluster, and then upgrade locales from
2.13-38+deb7u9 to 2.13-38+deb7u11. The database was working as before,
without requiring a restart. Even upgrading libc6+dependencies doesn't
break it.

Does that match what you were doing? (I see that you seem to have
LC_ALL set, that might complicate matters.)

What other packages were upgraded there?

The generic answer here is likely that if any of the low-level libc
packages are upgraded (which might include locales), a database
restart is required. I don't see that we can fix this on the
PostgreSQL side.

I'd additionally claim that unattended upgrades might be a bad idea.
(Note that in jessie, libc upgrades will ask you to restart
PostgreSQL. Unless I'm mistaken, in wheezy, that logic wasn't present
