pacman -Sy and pamac update.db.sig files
If a db.sig file is provided, pacman -Sy updates and verifies signatures, but pamac updates do not.
In pacman.conf, DatabaseOptional is the standard for SigLevel, and db.sig is not provided in the repository. In pacman -Sy, the standard behaviour is that if db.sig files exist, they are also downloaded and updated. However, they are not being updated by pamac udpate, which just calls _alpm_download. It would be better to have the same behaviour for db.sig files in pacman and pamac. Wouldn't it be better to make it standard behaviour to download the db.sig file if the SigLevel is DatabaseRequired or DatabaseOptional?
