hey, silly idea formed on half a cup of coffee.... if that base backup
is in the form of a copy of the data directory (as opposed to tar.gz or
something), could you 'update' it by pointing an instance of postgres at
it, and then playing the WAL archive into it, then shutting that
instance down? or would it be impossible to synchronize the ongoing
new WAL's from the master with the timeline of this?
