Deepthi, tech lead for Vitess, just published this RFC a few days ago: https://github.com/vitessio/vitess/issues/7084

Vitess plans to support PostgreSQL, but there is no work on that at this time.

on k8s there is:

- crunchydata - the thing crunchy is based on (well actually they are more based on the underlying things like patroni): zalando postgres operator https://github.com/zalando/postgres-operator, really really solid stuff

Not a DBA, but this seems comparable:

> stolon - PostgreSQL cloud native High Availability https://github.com/sorintlab/stolon

Citus does sharding as an extension for postgres.

If all you want is HA and FO there are simpler solutions like pgpool and pgbouncer etc.

CockroachDB uses pg protocol but doesn’t support all the features (close enough though).

Not a library but you can achieve the same with less work using amazon aurora postgres.

It's not the same, you can't scale out from 1 writer on Aurora.

And a boat load of money
