If the PostgreSQL database cluster is down (or has been deleted), pgstats in PyMunin 0.9.27 responds with an unhandled exception. Is that a design decision, or could pgstats perhaps exit a little more gracefully?
The unhandled Python exception is detected by the abrt daemon, so every five minutes the unhandled Python exception is logged to /var/log/messages:

(pgstats-5600 is a symbolic link pointing to /usr/share/munin/plugins/pgstats, of course. 5600 used to be the port number used by that former PostgreSQL instance.)
