Is it possible to use streaming replication across different platforms (OSX/linux)?
No, it is not possible - you have to use logical replication like Slony

As I read it, you must use a file system level base backup to setup the slave. I ran into problems trying pg_basebackup and, as was pointed out, that is not supported. So will a tarball or any other file system level copy work? Will I run into the same problems? alan
