Add it

One line: the newest 1.1

doze.hcl

module postgres "postgres" {
  version    = 18
  extensions = ["pg_duckdb"]
}

Pinned to an exact version

doze.hcl

module postgres "postgres" {
  version = 18
  extension "pg_duckdb" { version = "1.1" }
}

doze fetches the build for your Postgres major and platform once, checks its sha256, pins it in doze.lock and runs CREATE EXTENSION pg_duckdb. Nothing to install, the same on a Mac and on Linux. A newer pin later runs ALTER EXTENSION pg_duckdb UPDATE for you. It preloads: doze adds it to shared_preload_libraries and restarts the instance once when the set changes.
