For unknown reasons, our PG server died overnight. (PG 7.4.2, RedHat 8,
ext3 ordered data mode, and battery backed RAID5)  When it came back up, I
saw an unfamiliar line in the recovery output from Postgres:

Apr 20 11:28:14 postgres: [6203] LOG:  database system was interrupted at

Apr 20 11:28:20 postgres: [6203] LOG:  database system is ready

What's the significance of the "unexpected pageaddr" item?
