Greetings, * norbert poellmann (np@xxxxxx) wrote: > https://www.postgresql.org/docs/current/different-replication-solutions.html > is listing a shared disk solution for HA. Yeah. Frankly, it's bad advice and we should remove it. "Rapid failover" is a bit laughable compared to replication when you consider that crash recovery can take a very, very long time (depending on how much outstanding WAL has been written since the last checkpoint but with extended checkpoints and single-process WAL replay, crash recovery could be on the order of hours ...) and promoting an online replica takes only moments. Ditto for block-based replication. Probably should talk about WAL shipping more as "Physical Replication". At the least, physical replication should really be listed first and then logical replication, perhaps even in a distinct "included as part of PostgreSQL" section with everything else pushed down to "some other things exist that you could try"... Thanks, Stephen
