PostgreSQL

Runs PostgreSQL 14 – 18 · macOS & Linux · registry page ↗

A real PostgreSQL server per instance — no Docker. Declare roles, schemas, extensions and grants in HCL and doze converges them: creating what’s new, updating what changed, dropping what you removed. Boots on first connect, reaps when idle.

Usage

postgres "app" {
  version          = 18
  port             = 5432
  owner            = "app"
  encoding         = "UTF8"
  locale           = "en_US.UTF-8"
  connection_limit = 50
  comment          = "primary app database"
  shared_buffers   = "256MB"
  max_connections  = 100

  settings = {
    log_min_duration_statement = "200ms"
  }

  role "app" {
    password         = "app"
    login            = true
    createdb         = true
    connection_limit = 20
    member_of        = ["readers"]
  }

  role "readers" {
    login = false
  }

  schema "analytics" {
    owner = "app"
  }

  extension "pg_trgm" {}

  grant {
    role       = "app"
    privileges = ["ALL"]
    schema     = "analytics"
    objects    = "tables"
  }
}

Versions you can declare

The version = you write is the engine’s own version — the only version that’s yours. Declare a series and doze pins its newest published build, or declare an exact build; either way it’s fetched, verified, and pinned in doze.lock (so it never moves on its own).

version =	pins (today)	exact builds
14	14.23.0	24
15	15.18.0	19
16	16.14.0	15
17	17.10.0	11
18	18.4.0	5

Module releases

Machinery, for the curious: the plugin releases that provide this engine. doze selects the newest compatible one and pins it in doze.lock — you never write these. Older releases stay resolvable for pinned lockfiles.

0.2.2	14 · 15 · 16 · 17 · 18	3
