repmgr is a free software project developed by 2ndQuadrant for the
purpose of making it easier to build large numbers of replicated
PostgreSQL 9.0 standby servers. It simplifies:
* Creating new standbys using PostgreSQL 9.0 Streaming Replication.
* Analyzing replication lag that impacts both high availability and Hot
Standby queries.
* Maintenance tasks required to handle failover when a node is removed
from the standby cluster, either intentionally or via failure.
By providing a system daemon outside of the database to help coordinate
multi-node actions, repmgr makes putting many nodes into a cluster
easier to setup and manage.
repmgr currently targets UNIX-like systems, requiring access to the PGXS
interface for compiling PostgreSQL related code and the rsync utility
for efficient node syncronization. The main project page with periodic
snapshot releases is at http://projects.2ndquadrant.com/repmgr and we've
created a mailing list/forum to discuss user and development questions
related to the program.
The active development repository, including documentation about
building and using the program, is available at
https://github.com/greg2ndQuadrant/repmgr . Community contributions to
the project under its GPL v3 license are welcome. repmgr has been
actively deployed on sites all over the world during the time it's been
available, and a 1.01 release featuring bug fixes and additional feature
improvements is planned for release later this month.
