It is not clear to me to which logs you are referring: the commit logs
or the WALs? Anyway, transaction are numbered in an unique way around
the cluster, and therefore it does not matter on which database you
are going to run the transaction, it will not interfere with other
databases within the same cluster.
I don't get what advantage will give you having logs different for
each database/schema, considering that it is not clear what kind of
maintenance you are going to do on such logs. Can you please better
explain what is your aim and use case?
