Cluster architecture
We define topology, coordination components, connection and failover policies.

PostgreSQL Consulting - PostgreSQL Can't Stop
PostgreSQL cluster projects and support with Patroni, automatic failover and continuous protection observation.
PostgreSQL · Patroni and Automatic Failover
What is this service?
Patroni is one of the most used ways to orchestrate automatic failover in PostgreSQL, combining failure detection, replica promotion and integration with connection components.
Power Tuning designs cluster, quorum/coordination definition, integration with etcd or Consul, PgBouncer, replicas and test procedures. The goal is to turn high availability into a reliable routine, not a source of operational anxiety.
How we operate
How Power Tuning conducts this work
We work with diagnosis, execution plan, assisted implementation and result validation.
Assisted deployment
We configure Patroni, nodes, replicas, proxy and operational integration.
Promotion Test
We run failure and fallback scenarios to validate behavior and response time.
Support and monitoring
We monitor lag, role of nodes, events and cluster risk signals.
What is it for
When this service makes sense
The service gains value when the environment is no longer predictable, scalable or secure for the business.
Critical Systems
When PostgreSQL unavailability impacts billing, service or central operations.
Existing cluster with instability
When Patroni already exists, but the failing behavior does not inspire confidence.
Distributed environments
When you need to protect service across zones, sites, or regions.
Maintenance with less impact
When the company wants to reduce planned unavailability.
Expected results
What changes in practice
Our focus is to generate operational gains and reduce risk with indicators that the client can monitor.
Faster response to failure
The cluster gains more predictable behavior in real events.
More reliable protection
Failover no longer depends on improvisation or late intervention.
Better integrated connectivity
Applications and proxies respond better to the change in role between us.
More visibility
Lag, node status and cluster health are now monitored.
Advantages for the company
Why discuss this topic with experts
The company gains speed of response, technical governance and more predictability for business decisions.
PostgreSQL HA experience
We reduce cluster traps that usually appear only in the incident.
Operation runbooks
The team receives clear procedures for the event, return and maintenance.
Systemic view
We treat banking, coordination, proxy and application as a single delivery.
Risk-oriented monitoring
The operation starts to see signs that precede loss of protection.
