Trusted Postgres Architect

Trusted Postgres Architect (TPA) is an Ansible-based tool for deploying and managing Postgres clusters using EDB recommendations. Users describe a cluster’s topology and settings in declarative YAML. TPA can provision AWS EC2 instances or Docker containers, or use existing servers and virtual machines when connection details are supplied. It installs and configures Postgres and related pieces such as replication and backups; depending on the cluster design, these may include PGD, Barman, PgBouncer, repmgr and extensions. TPA can run tests tailored to the architecture and platform, apply configuration changes, handle switchovers and perform minor-version upgrades described as zero-downtime. Its configure documentation lists PostgreSQL, EDB Postgres Extended and EDB Postgres Advanced Server versions 13 through 18. It is free and open source for self-hosted Linux deployments. STIG and CIS configuration options are available, but EDB says they do not guarantee that a cluster meets those standards. TPA does not support major-version Postgres upgrades through its `tpaexec upgrade` command.

TPA covers deployment and ongoing cluster operations, including minor upgrades and switchovers. Plan major Postgres version changes separately, and treat the available security profiles as configuration options rather than compliance guarantees.

TPA suits teams that want to deploy Postgres clusters on self-hosted Linux infrastructure, from testbeds to production environments. It may also suit teams that need configuration automation, replication or cluster switchovers.

Trusted Postgres Architect (TPA) is EDB’s open-source Ansible orchestrator for building and operating PostgreSQL clusters. It is best suited to teams standardizing Linux or self-hosted deployments with declarative YAML, from testbeds through production. The trade-off is a capable operations layer that still requires a separate plan for major-version upgrades.

Overview

TPA turns a YAML description of topology and configuration into a working Postgres cluster. It can provision AWS EC2 instances and Docker containers, or configure existing servers and virtual machines when connection details are supplied. That makes it practical for repeatable builds across mixed infrastructure, although the resulting hosts and services remain your responsibility to operate.

Deployments can include PostgreSQL, replication, backups, and architecture-dependent components such as PGD, Barman, PgBouncer, repmgr, and Postgres extensions. EDB presents the same recommendations for quick testbeds and production environments. STIG and CIS options help apply security-oriented settings, but EDB does not treat those options as proof that a cluster meets either standard.

Key features

• Declarative cluster design: YAML records the cluster’s topology and settings in one deployment description. This favors teams that need reproducible environments and reviewable configuration rather than ad hoc server-by-server setup.
• Automated provisioning: TPA can create AWS EC2 and Docker resources or target infrastructure you already own. The choice is useful for hybrid workflows, while self-hosted operations still demand infrastructure expertise.
• Full stack installation: The tool installs and configures Postgres, replication, backups, and related services. Depending on architecture, PGD, Barman, PgBouncer, repmgr, and extensions can be coordinated as part of the same build.
• Validation: Architecture- and platform-specific tests run against a deployed cluster. That gives operators a built-in check after deployment instead of relying solely on configuration review.
• Ongoing operations: TPA handles configuration changes, switchovers, and minor-version upgrades described as zero-downtime. It does not perform major Postgres version upgrades through tpaexec upgrade, so a separate migration process is essential.
• Extensibility: Custom Ansible commands, tests, and deployment hooks let experienced teams adapt the workflow to local procedures. This flexibility is valuable, but it also places more maintenance and responsibility on the operator.
• Credential handling: A cluster-specific Ansible Vault password encrypts sensitive variables, and the documented system-keyring option stores that password in a keyring backend. These mechanisms improve secret handling without removing the need for broader access controls.
• Version coverage: Configuration documentation covers PostgreSQL, EDB Postgres Extended, and EDB Postgres Advanced Server versions 13 through 18. Automation Platform deployment and upgrade steps are supported through Red Hat Ansible Automation Platform only on bare-metal platforms.

Pricing

TPA is free and open source. The “Trusted Postgres Architect” plan costs nothing, with no seat, quota, trial, or renewal charge stated. That makes it a straightforward choice for teams able to supply their own Linux or self-hosted infrastructure and operational expertise. There is no cheaper tier that trades away automation; the main cost is the engineering time required to run and extend the platform, plus any infrastructure it provisions.

Platforms

TPA runs on Linux in self-hosted deployments, with a hybrid deployment model. It supports PostgreSQL and EDB Postgres Advanced Server, and its supported-database listing also includes Postgres-XL as a subscriber. Provisioning can span AWS EC2, Docker, existing servers, and virtual machines. High-availability management, automated provisioning, roles and permissions, audit logging, change data capture, and two-way replication are listed capabilities.

Who it's for

Choose TPA if you operate Postgres clusters and want infrastructure-as-code, repeatable topology, integrated replication and backup setup, and controlled switchovers or minor upgrades. It is particularly suitable for platform engineers who can work with Ansible and maintain self-hosted systems. It is a weaker fit if you need a managed service, a graphical administration experience, or an upgrade command that handles major Postgres releases end to end.

Pros and cons

Pros

• Free, open-source orchestration: There is no license fee for adopting the tool or scaling its deployment pattern.
• Repeatable hybrid provisioning: The same declarative approach can cover cloud instances, containers, and existing machines.
• Broad cluster scope: Postgres, replication, backups, pooling, failover tooling, and extensions can be coordinated in one architecture.
• Operational automation: Configuration changes, switchovers, tests, and minor upgrades reduce manual cluster work.

Cons

• No major-version upgrade support in tpaexec upgrade: You must design and execute a separate migration path for major releases.
• Security profiles are not compliance guarantees: STIG and CIS settings require independent compliance validation.
• Infrastructure remains self-managed: TPA automates deployment, not the underlying ownership and day-to-day operation of hosts.
• Automation Platform limitation: Red Hat Ansible Automation Platform integration is limited to bare-metal platforms.

Alternatives

For a lightweight web database administrator, phpLiteAdmin is free and self-hosted, centered on PHP and SQLite rather than Postgres cluster orchestration. Pick ClusterControl when you want a free Community plan for deployment and monitoring or a paid self-serve tier at €250 a month. Neo4j is the alternative for graph databases, with a free AuraDB plan and trial. Choose YugabyteDB Anywhere for a distributed database platform with a free evaluation license lasting up to 32 consecutive calendar days; production requires a commercial license. Adminer is a free, self-hosted web administration tool for supported PHP environments, not a Postgres cluster deployment system. DbNinja offers a freemium, browser-based database administration option across major desktop platforms. OpenEverest is fully open source with no licensing fees for customizable deployment. phpMyAdmin is free web administration software for MySQL and MariaDB.

Verdict

Trusted Postgres Architect is a strong choice for technically capable teams that want free, repeatable Postgres cluster deployment and ongoing minor-version operations across self-hosted or hybrid infrastructure. Choose it for declarative control and integrated HA-oriented components; look elsewhere if you need managed hosting, a simpler administration tool, or built-in major-version upgrade execution.
