PostgreSQL

What it does: PostgreSQL is an open source object-relational database system that uses and extends SQL to store and scale complex data workloads.

Integrity and transactions: Features include primary and foreign keys, constraints, explicit and advisory locks, transactions, savepoints, and all SQL-standard transaction isolation levels.
Performance: PostgreSQL includes multiple index types, a query planner and optimizer, parallel query processing, table partitioning, just-in-time expression compilation, and asynchronous I/O.
Recovery and replication: It supports write-ahead logging, asynchronous, synchronous, and logical replication, point-in-time recovery, and active standbys.
Security: Listed security features include GSSAPI, LDAP, SCRAM-SHA-256, certificate and OAuth 2.0 authentication, access controls, row- and column-level security, and multi-factor authentication.
Extensions and integrations: PostgreSQL supports extensions such as PostGIS, procedural languages, and foreign data wrappers that connect to other databases or streams through SQL.

License: The PostgreSQL License permits use, copying, modification, and distribution for any purpose without a fee or written agreement, subject to its conditions.
