spock and pgedge are cool, but they are NOT open source (and they try hard to make it look like they are). It is under the Confluent license (with s/confluent/pgedge/), basically a source-available-but-Amazon-cannot-use-it ki

OTOH the PolarDB specific changes seem to be contained enough that if you decide to run it in production, you can probably just apply most of the changes from the v11 branch yourself. But I agree it's not a very good look to code-drop

I don't know, maybe you should. CockroachDB seems to be a distributed database system written in Go which has implemented a Postgres query/wire protocol compatibility layer. PolarDB is a Postgres fork actually using the Postgres c

Looks like it, yeah. Also, Postgres 12 introduced pluggable storage, which might help to implement a shared-nothing architecture without huge changes to vanilla Postgres (I haven't looked at how large their delta is)

But that's also true for e.g. the US and russian presidents, no? Except those actually hold real power. In practise, most german presidents will just be way too old four years after they leave office to be a viable candidate, and it lo

Notably, that feature got written by somebody from Salesforce (I assume on their work time, but not sure), and finished up by a Postgres major contributor. It might be the first major contribution from Salesforce outside of all the stuff To

There are no good multi-master solution with a HA focus available for Postgres, at least no open source ones. The patroni project checks most of your other requirements: docker/containerized design with leader election/continuing

To the contrary, I think journalists often only get to advise on the headline, and the editors then choose/override one to their liking.

patroni builds upon etcd and (optionally) haproxy, two rather mature pieces of infrastructure (which can both be made HA on their own if SPOFs are to be avoided). I understand where you are coming from, but having this kind of multi-server-

Note that starting from Postgres 10 (which this thread is about), you don't need to adjust wal_level and max_wal_senders (or max_replication_slots, for that matter) anymore. You still have to enable hot_standby=on on the standbys, thou
