So, you're using a version released almost 2 years ago, missing 8 minor
releases worth of bug fixes. In general, if you have a problem you should just
blindly update to the latest minor version, otherwise it's highly unlikely that
anyone will look at your problem.

Really? This error is displayed if the server is doing some automatic recovery
after an unclean shutdown. Could be an unrecoverable error like IO error on
the WALs, or just anything fixed in the last 2 years.
You should check for any message with PANIC/FATAL log level too.

Was it 7 uninterrupted hours or did your database keeps being stopped in an
unclean way for 7 hours? More details from the logs would help, you could also
see https://wiki.postgresql.org/wiki/Guide_to_reporting_problems. But above
all you should consider updating to the latest minor version as soon as
possible.
