PS4 Rebuild Database?

Guys I'm a little worried/and or paranoid here. I just finished downloading the new 1.70 update, and when it finished installing I saw a message come up on screen saying something like "Rebuilding the database". After that it started up like normal, what gives?

Is this normal or has something been corrupted within my system? Did anyone else see this message after the update? Thanks.

Yep happened here as well. Nothing to be worried about. Rebuilding the database is fine, in fact it can fix issues such as when PS trophy syncs stop working.

Awesome, thanks. Must of been part of the update I guess.
