WAL logs - do they operate at a database or cluster level?

Hi again and thanks for your help on my previous post.

Now I ask:
From the docs it seems that if I wish to enable WAL archiving for a database I change the settings of  archive_mode  and archive_command

in the postgresql.conf  file.
Am I right to assume that this enables WAL logging at a cluster level i.e. EVERY database in that cluster goes into WAL archive mode?

Thanks
