After restart reports deleted

hi all,

why after restart, foreman remove last 2 weeks reports ?
that mean if I have
today reports

2 weeks ago

and I restart the server
I see the under reports for hots:
1min ago
2 weeks ago

Does anyonw know why and where can I change this variable ?

thank you all

No one have an answer!

Ill explain a little bit more:
When I now run shutdown -r now the reports are gone for latest two weeks!
Is there anything with Foreman Postgresql ? I mean do I have to do anything before reboot ?

I use Foreman with Puppet

thank you all
