Nope, that KB is related to problems with MS-SQL.
The jobs and the stored procedures are actually there, and I compared them to the scripts found in C:\Program Files\VMware\Infrastructure\VirtualCenter Server\sql.
The effect I see in the vSphere Client is: Real time stats and daily stats are available, weekly stats are missing, and monthly and yearly stats are shown up to the time where I did the upgrade.
I've also seen the suggestion in KB2007388 to truncate some tables, but I'd like to understand first what's going on before dropping any data.
