PostgreSQL has earned its reputation as the most capable open-source relational database. It supports advanced features like JSONB columns, full-text search, window functions, CTEs, and extensions like PostGIS for geospatial data. PostgreSQL's MVCC architecture provides excellent concurrent performance, and its WAL-based replication enables reliable high availability setups. The database has become the default choice for new projects that need a relational store, largely displacing MySQL in the startup ecosystem. Its extensibility through custom types, functions, and extensions means it can serve as a document store, time-series database, or search engine in addition to its traditional relational role.
