## What it is
Kubegres is a Kubernetes operator written in Go that deploys and manages clusters of PostgreSQL instances with streaming replication, automatic failover, and scheduled backups. It provides a simple custom resource (kind: Kubegres) built on Kubebuilder, keeping a minimal codebase compared to other Postgres operators.

## Use cases
- deploy a postgres cluster on kubernetes
- set up postgres streaming replication with primary and replicas
- automatic failover when primary postgres pod crashes
- schedule regular postgres data backups to a volume
- manage many self-contained postgres clusters via simple YAML
- run postgres in production on kubernetes without custom docker images

## When to choose
- you want a minimalist, easy-to-understand Postgres operator for Kubernetes
- you need out-of-the-box streaming replication and failover
- you want to use official Postgres Docker images without custom images
- you need to run one or many small-to-medium Postgres clusters in production

## When to avoid
- you need advanced features like point-in-time recovery, connection pooling, or horizontal scaling beyond streaming replicas
- you are not running on Kubernetes
- you need a highly feature-rich operator with extensive ecosystem support
- you require managed database services rather than self-managed clusters
