Lists: pgsql-performance looks like the slave machine has run out of space and that caused
the xlog files to pile up on the master. do I prevent such all of the shipped WAL segments from remaining
on the slave machine? Do I need to retain every single one? Can they be
safely removed after the slave machine has restored the particular segment?
