PostgreSQL is an object-relational database system that has the features of traditional proprietary database systems with enhancements to be found in next-generation DBMS systems. PostgreSQL is free and the complete source code is available.Features PostgreSQL has most features present in large proprietary DBMSs, like transactions, subselects, triggers, views, foreign key referential integrity, and sophisticated locking. Some features they do not have, like user-defined types, inheritance, rules, and multi-version concurrency control to reduce lock contention. Performance PostgreSQL's performance is comparable to other proprietary and open source databases. It is faster for some things, slower for others. Performance is usually +/-10% compared to other databases. Reliability DBMS must be reliable, or it is worthless. Release well-tested, stable code that has a minimum of bugs. Each release has at least one month of beta testing, and release history shows that provide stable, solid releases that are ready for production use. Compare favorably to other database software in this area.
