pgAdmin vs Trusted Postgres Architect

pgAdmin is a graphical tool for administering, developing with, and monitoring PostgreSQL databases. It runs as desktop software or in server mode, where multiple users can access it over the web. It supports PostgreSQL and EDB Postgres Advanced Server versions supported at the time each pgAdmin release is issued. Query tools include syntax highlighting, a data grid, graphical query plans, schema diff, an ERD tool, and a procedural language debugger. Users can manage common database objects and inspect their SQL definitions, properties, dependencies, and available statistics. Maintenance features include a monitoring dashboard, auto-vacuum management, and on-demand backup, restore, vacuum, and analyze operations. It also supports SSH tunneling, data editing, query history, and binary, CSV, or text result exports. The free plan costs nothing under the PostgreSQL Licence. Downloads include Windows and macOS installers, Linux packages, Docker, a Python wheel, and source code. Only the latest release is supported; there are no long-term stable versions.

Trusted Postgres Architect (TPA) is a free, Ansible-based tool for deploying and managing Postgres clusters using EDB recommendations. Users describe cluster topology and configuration in declarative YAML. TPA can provision AWS EC2 instances and Docker containers, or use existing servers and virtual machines when connection details are supplied. It installs and configures Postgres and related components, including replication and backups; architecture-dependent components can include PGD, Barman, PgBouncer, repmgr, and Postgres extensions. TPA can run tests specific to the cluster architecture and platform, apply configuration changes, perform switchovers, and carry out documented zero-downtime minor-version upgrades. Its configuration documentation lists PostgreSQL, EDB Postgres Extended, and EDB Postgres Advanced Server versions 13 through 18. The tool supports self-hosted Linux deployments and offers STIG and CIS configuration options, though these do not guarantee that a cluster meets those standards. TPA does not support major-version Postgres upgrades through the `tpaexec upgrade` command. Users can extend it with custom Ansible commands, tests, and deployment hook scripts.
