2.0 -> 2.2 no history

[Jason]

I'm using postgres and table partitioning...

I've created a test server where I've put a mirror of my zabbix database and then installed 2.2 onto this test machine.

After starting zabbix the upgrade processes very quickly, but when I login I can just see the hosts... All historical data is lost. Has something gone wrong on the upgrade?

Repeated with a fresh backup and all worked ok. Seems like the first backup was missing some data.
