Why PostgreSQL is our default database, how to design it so it stays fast, and what a managed setup looks like.

Clear answer
PostgreSQL is a free, open-source relational database known for keeping data correct. It handles orders and payments safely, runs complex reports, and can also store JSON, location and AI search data, so most products need only one database. Managed versions on AWS, Google Cloud and Azure take care of backups and updates.
summary
Important points
Your data stays correct. Transactions mean an order and its payment are saved together, or not at all.
One database, many jobs. JSON, maps (PostGIS) and AI search (pgvector) often remove the need for a second database.
Design tables before screens. A clear schema up front saves weeks of rework and painful data migrations later.
Index for the queries you actually run. Most slow apps are missing an index, not short of a bigger server.
Use a managed service with point-in-time backups. A bad delete becomes a short restore, not a lost day.

Expand: the full detail
PostgreSQL, often called Postgres, is an open-source relational database that has been developed for more than 30 years. Data lives in tables linked by keys and is queried with SQL. It follows ACID rules, so every change is complete and consistent even if a server fails half-way through.
The app talks to PostgreSQL through a connection pool. Writes go to the primary database; heavy reports can run on read replicas so they never slow the app, and continuous backups let you restore to any moment.
| Role | When | Focus |
|---|---|---|
| Backend developer | Weeks 1–4 | Schema, queries, migrations |
| Database architect / DBA | Weeks 1–2 | Design review, indexing plan |
| DevOps | Weeks 3–4 | Managed database, backups |
| QA | Weeks 3–4 | Data and migration tests |
| Project manager | Throughout | Scope and sign-off |
PostgreSQL itself is free; you pay for the server or managed service it runs on. [Use the calculator for a live number.]
Yes. It is open source under a permissive licence; you only pay for the server or managed service it runs on.
Both are solid. PostgreSQL offers more for complex queries, JSON and extensions; MySQL is simpler and common on WordPress hosting.
PostgreSQL suits connected business data; MongoDB suits loosely structured documents. PostgreSQL’s JSON support covers many document cases.
Yes. With good indexes, connection pooling and read replicas, it runs very large production systems.
