[GENERAL] streaming replication across platforms

Is it possible to use streaming replication across different platforms (OSX/linux)? 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 syste

[GENERAL] 'missing' data on replicate

I have 4 machines in a cluster: 1 master & 2 replicates (hot standby mode) on OSX, 1 replicate (hot standby mode) on Linux (centos6.5). All replicates were created with pg_basebackup (+ X option). I have a table that returns no results when queried by the primary key on the replicate running o
