[5.0 Upgrade] Database history tables upgraded: No, even after double.sql

[daftu]

Hi,
I've upgraded from 4.4 to 5.0
After running zabbix server for the first time it upgraded database but without double conversion (as stated in release notes https://www.zabbix.com/documentation...rade_notes_500).
Then I ran database/postgresql/double.sql to convert value_* fields in history and trends.

Unfortunately frontend still says "Database history tables upgraded: No", even after zabbix server restart.

You need also to update/insert

$DB['DOUBLE_IEEE754'] = 'true'; 

into zabbix.conf.php of the frontend configuration
