Cascading replication and archive_command

apparently a few users were puzzled that archive_command is ignored on slave servers, which comes as a surprise since streaming replication will work fine from slaves and as far as I’ve checked the documentation also doesn’t point out the fact that archive_command gets a different treatment.

Is this intentional or an oversight? Should this be fixed in the code (feature parity to SR) or in the documentation making this more explicit?

best,

Michael
