What is PostgreSQL? Nedir?
PostgreSQL is a powerful open-source relational database system known for its advanced features and standards compliance.
PostgreSQL originated from Michael Stonebraker's POSTGRES project at UC Berkeley in 1986. Known as 'the world's most advanced open-source database,' PostgreSQL is one of the most SQL-standard compliant databases available. PostgreSQL's strengths include advanced data types (JSON/JSONB, array, hstore, range, geometric), full-text search, CTEs (Common Table Expressions), window functions, materialized views, foreign data wrappers, and advanced indexing (B-tree, GiST, GIN, BRIN). PostgreSQL provides high concurrency through MVCC (Multi-Version Concurrency Control). Logical and streaming replication, tablespace management, point-in-time recovery, and pg_dump/pg_restore offer robust backup solutions. The PostGIS extension enables geospatial data processing, and TimescaleDB handles time-series data. Apple, Instagram, Spotify, Reddit, Twitch, and The Guardian use PostgreSQL. Its popularity has rapidly grown compared to MySQL in recent years and has become the default choice for many new projects.
