PostgreSQL

aid: postgresql
name: PostgreSQL
description: PostgreSQL is a powerful, open-source object-relational database system with over 35 years of active development.
  It provides advanced SQL compliance, ACID transactions, and extensibility. PostgreSQL exposes a binary wire protocol via
  libpq and language bindings rather than a public HTTP REST API, so there is no canonical OpenAPI specification. HTTP access
  is typically layered on top via PostgREST, Hasura, or application code.
