Upgrading from 6.4.1 to 7.0.0alpha5 fails during the database upgrade with:

 44973:20230928:184943.699 starting automatic database upgrade

 44973:20230928:184943.700 database upgrade failed on patch 06050008

The 'value' field in the history table is already 'double precision' so wasn't expecting this DB patch to be applied:

zabbix=# \d history
