[0.1.0] - 2026-05-12

Added

  • PgSpawner GenServer — starts Postgres as a BEAM-owned child via Port.open/2, with a shell watchdog that guarantees cleanup on SIGKILL.
  • Guest mode: joins an already-running Postgres without owning the lifecycle.
  • :log_file option — Postgres output goes to <pgdata>/postgres.log by default instead of the BEAM console. Pass :stdio to restore console output, nil to discard.
  • OTP Application auto-start — adding :pg_spawner to deps is sufficient to start Postgres on app boot. Defaults: port: 15432, pgdata: "priv/db/data". Override via config :pg_spawner, .... Set pgdata: false to disable.
  • Auto-initdb: PgSpawner bootstraps pgdata on first run if no PG_VERSION is present. No shellHook ceremony required.
