Hello,
To save some disk space, we are disabling generating sqlite databases for repositories which we think is not necessary [1]. I believe that it should not affect you, but we published this change to our stg instance [2], so you can try whether this change won't break your projects on certain chroots.
The PR changing this - https://github.com/fedora-copr/copr/pull/2570
