Though "replication" is a single term, there are two major replication
technologies. Multi-master replication allows read/write queries to be
- sent to multiple replicated computers. This capability has a serious
- performance impact. Pgcluster is the most popular such solution
- available for PostgreSQL. Master-slave replication allows a single
- master to receive read/write queries, with slaves able to accept only
- read/SELECT queries. The most popular master-slave PostgreSQL
- replication solution is Slony. There are also commercial and
- hardware-based replication solutions available.
