PostgreSQL is a powerful, 100% free and open source, object-relational database system, with over 30 years of active development. It has a strong reputation for reliability, feature robustness, and performance.
PostgreSQL is popular with developers due to numerous features such as: native partitioning, parallel query, support of foreign data wrappers, powerful JSON features, streaming and logical replication and the availability of many open source tools for HA, backups and monitoring.
This white paper looks at the features and benefits of PostgreSQL and presents some practical usage examples. We also examine how PostgreSQL can be useful for companies looking to migrate from Oracle.
