Historically the project policy has been to avoid putting replication into core PostgreSQL, so as to leave room for development of competing solutions [...] However, it is becoming clear that this policy is hindering acceptance of PostgreSQL to too great an extent, compared to the benefit it offers to the add-on replication projects.
