PostgreSQL

aid: postgres
name: PostgreSQL
description: PostgreSQL is a powerful, open-source object-relational database system with over 35 years of active development
  that has earned a strong reputation for reliability, feature robustness, and performance. It supports advanced SQL features,
  JSON, full-text search, custom data types, extensions, and transactional DDL. PostgreSQL does not expose a native HTTP REST
  API; client applications connect via the libpq C client library, JDBC, ODBC, or one of dozens of language-specific drivers
  using the PostgreSQL wire protocol (default port 5432).

  name: PostgreSQL Wire Protocol
  description: The PostgreSQL frontend/backend protocol is the low-level message-based protocol used by all client drivers
    (libpq, JDBC, ODBC, psycopg, pgx, node-postgres, etc.) to communicate with the PostgreSQL server over TCP/IP or Unix sockets.
    Authentication supports password, SCRAM-SHA-256, MD5, GSSAPI, SSPI, certificate, LDAP, and other pluggable methods.
