pg_stop_backup deletes the previous backup history file from pg_xlog.
So replication of a backup history file would fail if just one new
online-backup is caused after the base-backup for the standby is taken.
This is too aggressive deletion policy for Streaming Replication, I think.
So I'd like to change pg_stop_backup so as to delete only backup
history files of four or more generations ago (four is enough?).
Thought?
