PostgreSQL

The world's most advanced open-source relational database.

PostgreSQL is the most advanced open-source relational database system, known for its reliability, robustness, and extensibility. It supports advanced data types (JSON, arrays, hstore), full-text search, geographic queries (PostGIS), and transactional DDL, features that make it suitable for virtually any data modeling requirement.

PostgreSQL is our default database for all projects. Its reliability, SQL compliance, and advanced features (JSONB, full-text search, CTEs) provide the foundation for complex data models without needing specialized databases.

What we use it for

  • Transactional web application databases
  • Complex data models with relationships
  • Full-text search and content indexing
  • Geographic data with PostGIS
  • JSON document storage with JSONB
  • Analytics and reporting databases

What it gives us

  • Advanced Data TypesJSONB, arrays, ranges, enums, and custom types for modeling any data structure natively.
  • Full-Text SearchBuilt-in full-text search with ranking, stemming, and language support, no external search engine needed.
  • ACID ComplianceFull transaction support with serializable isolation for data integrity in critical applications.
  • ExtensionsPostGIS for geospatial, TimescaleDB for time-series, pgvector for AI embeddings, extend without replacing.

Questions we get asked

PostgreSQL vs MySQL, which is better?
PostgreSQL is more feature-rich with better SQL compliance, advanced types, and extensibility. MySQL is simpler and faster for basic read-heavy workloads. We recommend PostgreSQL for new projects.
Is PostgreSQL free?
Yes. PostgreSQL is free and open-source with no licensing costs, no feature limitations, and no vendor lock-in. Managed hosting is available from many providers.
Can PostgreSQL handle large datasets?
Yes. PostgreSQL handles databases of several terabytes routinely. With partitioning, indexing, and read replicas, it scales to petabyte-level workloads.
Where do you host PostgreSQL?
We typically use Supabase for managed PostgreSQL with built-in backups, monitoring, and connection pooling. For AWS deployments, we use Amazon RDS PostgreSQL.
