Thu Apr 11 07:27:29 UTC 2013: There is a pretty serious update of PostgreSQL to be done for security reasons. Indefero will be done for a couple of minutes the time to update the server. I am sorry this is an unplanned update.
Thu Apr 11 07:30:54 UTC 2013: The slave has been updated and is correctly picking up the updates from master, now going to update the master. From the slave update sequence you can expect about 2 minutes downtime of Indefero.
Thu Apr 11 07:33:36 UTC 2013: The master has been updated, the effective downtime was less than 20 seconds.
