Purpose
Compare binary replication tools for PostgreSQL for features and ease of use.
OmniPITR
OmniPITR Demo of a simple replication setup with OmniPITR
Summary of Features:
- Creating PITR backups
- Restoring a PITR backup for DR
- Creating replicas (by untarring backups)
- Monitoring of replicas
- Supports 'pause removal' of WAL during a backup (nice!)
- BSD license
Install notes:
- No packaging, perl
- No documented support for streaming replication
- Uses an odd format for omnipitr logfile naming
- No configuration file option (instead of using long command-line options)
repmgr
Supported features:
- Setting up new replicas/hot_standby with streaming replication
- Making base backups
- Failover (automated, or not, including redirecting replicas to connect to a new master after failover)
- Lag monitoring (repmgrd)
- A "witness" DB server for monitoring (typically on a replica)
- License: GPLv3
Install notes:
- Written in C
- Installs like a typical UNIX utility out of postgresql/contrib source tree (make USE_PGXS=1; make USE_PGXS=1 install)
- Developed on Debian systems, so support for package is present. Did not find an Ubuntu package for repmgr, however.
- Detailed docs are in the README for installing on many Linux platforms
- Doesn't appear to be supported on Mac OS X
