Why Postgres?

  • PostgreSQL supports most of the major features of SQL:2016. Out of 177 mandatory features required for full Core conformance, PostgreSQL conforms to at least 170.

  • Scales Vertically and Horizontally with tools such as Citus (
  • Postgres supports RLS (Row Level Security) allowing you to implement authorization at the database level.
  • It can support many 1000's of transaction per second running on commodity hardware.

  • Postgres has earned a strong reputation for its proven architecture, reliability, data integrity, robust feature set, extensibility, and the dedication of the open source community behind the software to consistently deliver performant and innovative solutions.
