## What it is
PostDock provides Dockerfiles and orchestration examples for running a highly available PostgreSQL streaming replication cluster with Pgpool load balancing and Barman backups. It supports Docker Compose, Docker Swarm, Kubernetes, and cloud environments with self-healing and automated failover.

## Use cases
- set up a highly available postgres cluster in docker
- postgres streaming replication with automatic failover
- run postgresql on kubernetes with self healing
- load balance postgres reads with pgpool
- configure postgres backups and point-in-time recovery with barman
- avoid split brain in a replicated postgres cluster

## When to choose
- you need a self-contained, dockerized Postgres HA cluster with replication, pooling, and backups in one project
- you want examples for Docker Compose, Swarm, and Kubernetes deployment
- you need monitoring exporters for all cluster components

## When to avoid
- you use a managed Postgres service with built-in HA
- you need actively maintained tooling - the latest release is from 2020
- you prefer modern operators like CloudNativePG or Patroni-based stacks

## Facets
- artifact type: infra-config
- maturity: maintenance
- function: database, deployment, monitoring, backup, container-orchestration
- domain: databases, self-hosted, microservices
- platform: self-hosted, cloud
