PostgreSQL is an open-source relational database management system (RDBMS) that supports SQL for relational and JSON for non-relational querying. It is designed to handle a range of workloads, from single-machine applications to large internet-facing applications with many concurrent users.

About Postgresql
PostgreSQL originated in 1986 at the University of California, Berkeley, as a part of the POSTGRES project led by Professor Michael Stonebraker. It was created to address limitations in existing database systems and to support complex data types and relationships. The first version was released in 1989, and it evolved into an open-source project named PostgreSQL in 1996.
Strengths of PostgreSQL include advanced features like ACID compliance, support for complex queries, extensibility, and strong community support. Weaknesses involve potentially slower performance for certain write-heavy applications and a steeper learning curve. Competitors include MySQL, MariaDB, Oracle Database, and Microsoft SQL Server.
