#33 Database does not re-connect

[Michael Nash]

As far as I can tell, if the connection to the database is lost
(e.g. the db server goes down or is restarted), the default
persistent service will not re-establish the connection, but must
itself be re-started. It should check for a dead connection, then
simply drop the connection and try again for the next request -
the log shows that the container is "unable to return the
component", without much detail. DB in use at the time was
Postgres.
