Next Steps with PGD v5

Going further with your PGD cluster


In this quick start, we created a single region cluster of high availability Postgres databases. This is the, Always On Single Location architecture, one of a range of available PGD architectures. Other architectures include Always On Multi-Location, with clusters in multiple data centers working together, and variations of both with witness nodes enhancing resilience. Read more in architectural options.

Postgres versions

In this quick start, we deployed EDB Postgres Advanced Server (EPAS) to the database nodes. PGD is able to deploy a three different kinds of Postgres distributions, EPAS, EDB Postgres Extended Server and open-source PostgreSQL. The selection of database affects PGD, offering different capabilities dependant on server.

  • Open-source PostgreSQL does not support CAMO
  • EDB Postgres Extended Server supports CAMO, but does not offer Oracle compatibility
  • EDB Postgres Advanced Server supports CAMO and offers optional Oracle compatibility

  • Learn PGD's terminology - from Asynchronous Replication to Write Scalability
  • Find out how applications work with PGD and how common Postgres features like sequences are globally distributed
  • Discover how PGD supports rolling upgrades of your clusters
  • Take control of routing and use SQL to control the PGD Proxies
  • Engage with the PGD CLI to manage and monitor your cluster

Deprovisioning the cluster

When you're done testing the cluster, you'll want to deprovision it.

  • With a Docker deployment, deprovisioning tears down the Docker containers, network, and other local configuration.
  • With an AWS deployment, it will remove the EC2 instances, VPC configuration and other associated resources. Note that it will leave the S3 bucket it create; this will have to be manually removed.
