A friend contacted me today, asking me “What are the best practices for failover with Postgres?” And he mentioned pgpool-II.<\/p>\n
He was interested in 9.0, since 9.1 hasn’t been released yet.

I’ve also seen people use heartbeat (I guess pacemaker<\/a> now?). I think either works fine. The frustrating bit is that we don’t have the ability to refresh the failed system easily. <\/p>\n There’s also repmgr: https:\/\/github.com\/greg2ndQuadrant\/repmgr<\/a><\/p>\n It’s new, but might be worth exploring.\n<\/p><\/blockquote>\n I started an High Availability<\/a> page on the PostgreSQL wiki.
