Setting up highly available PostgreSQL instances can be tricky, which is why we like Patroni — it helps us speed up the setup of PostgreSQL clusters. Stolon is another tool that we've used successfully to run high-availability (HA) clusters of PostgreSQL instances in production using Kubernetes. Although PostgreSQL supports streaming replication out of the box, the challenge in an HA setup is to assure that the clients always connect to the current master. We like that Stolon enforces the connection to the right PostgreSQL master by actively closing connections to unelected masters and routing requests to the active one.
