Well, I see that I'm late to give the information :) Thank you to pointing me to this, but I have now some other questions now...
How can I see the timezone of the DB ?
When it says "all machines", do you confirm that this is physical machines, not VMs ?
May I apply the solution given on access.redhat or not, as there is no more messages since 3AM ?
And, last question but not least, can this timezone be changed on the machines (and DB ?) without issue ?

Hi,
 
Please see here
https://www.ovirt.org/documentation/data-warehouse/Data_Collection_Setup_and_Reports_Installation_Overview/
 
"It is recommended that you set the system time zone for all machines in your Data Warehouse deployment to UTC. This ensures that data collection is not interrupted by variations in your local time zone: for example, a change from summer time to winter time."
 
What timezone is your DB configured to?
 
Best,

and, coincidence, here in France we have change to winter hour at... 2AM :) So regarding this post:
https://access.redhat.com/solutions/3338001
speaking about a time problem, I've supposed that this is related ! No ? access.redhat says that the cause was not yet determined, but maybe it can be interesting to propose this cause ? But the bug is actually closed.

Question : does this repair all alone (as there is no more messages after 3AM) or may I applied the solution with postgres updates (I must say that I'm not very enthousiast for that...) ?

Regards,
