Introduction

PostRESP — PostgreSQL that speaks Redis (Redis/Valkey-compatible RESP), storage and protocol co-located in one process.

For the product pitch (self-hosters, small teams, compose-file story), see the marketing home. This page is the operator docs entry point.

Install the extensions, preload the gateway host, and Redis clients talk RESP to Postgres — storage and protocol in one process. The same gateway can also run as a standalone service next to Postgres when you need that deployment shape.

# Preferred: everything inside PostgreSQL
redis-cli :6379 → in-process RESP gateway → pgresp.* SQL → Postgres

# Also supported: gateway as an external service
redis-cli :6379 → standalone redis_gateway → same pgresp.* SQL → Postgres

Product goal: CREATE EXTENSION (+ preload) and you’re speaking Redis — no separate app tier required for the common case.

What you get

Piece	Role
`pg_resp`	SQL storage extension — schema `pgresp`
`pg_resp_gw_host`	In-process RESP listener inside Postgres (primary path)
`pg_cron`	Schedules active TTL deletion so expired keys are cleaned up in the background
`pg_prewarm`	Reloads recently used `pgresp.*` data into memory after a Postgres restart
Standalone `redis_gateway`	Same protocol core, run as a separate process when useful

Keys live in schema pgresp. Product extension names remain pg_resp / pg_resp_gw_host. Docker enables pg_cron and pg_prewarm by default — see Commands › TTL and Buffer cache prewarm.

Next steps

Getting Started

Install via Docker or Postgres extensions, verify with redis-cli, then connect your app.

Architecture

How storage, the RESP gateway, and deployment shapes fit together.

Storage modes

Choose unlogged or logged mode for your durability trade-offs.

Buffer cache prewarm

Reload recently used keys into memory after a Postgres restart.

Authentication

Postgres-backed Redis AUTH — on by default; opt out for open Redis-like access.

Verified apps

Application smoke tests — Immich, Outline, and other Postgres + Redis stacks.

Compatibility

Redis compatibility progress against the full Valkey test suite.

Benchmarks

Throughput vs Valkey across durability pairings — and how to read the numbers.
