PostgreSQL

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).

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile PostgreSQL

Each block below is one kind of artifact we hold for PostgreSQL. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 4

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

PostgreSQL Wire Protocol

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...

libpq C Client Library

libpq is the official C application programmer's interface to PostgreSQL and the underlying library used by most other PostgreSQL client interfaces. It provides connection manag...

PostgreSQL JDBC Driver

The official Type 4 JDBC driver for PostgreSQL enables Java applications to connect to PostgreSQL using the standard JDBC API. It supports connection pooling, prepared statement...

PostgreSQL ODBC Driver (psqlODBC)

The official ODBC driver for PostgreSQL providing Open Database Connectivity for Windows, Linux, and macOS applications including Microsoft Office, Tableau, Power BI, and other ...

GraphQL 1

Where a provider ships GraphQL, the schema is the contract. We profile it alongside the REST surface so the whole interface is legible in one place.

Security Posture 1

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Every other property we hold for PostgreSQL — documentation, portals, status pages, policies, and corporate surface — grouped by the job it does, following the integrator's arc from getting started to running in production.
