taut-pg

Postgres support package for Taut.

This package is intentionally separate from the core taut-chat distribution. It installs simplebroker-pg in the same environment as the taut CLI so .taut.toml can select the public SimpleBroker Postgres backend.

Requirements

  • Python 3.11+
  • PostgreSQL
  • A dedicated schema for Taut and SimpleBroker tables
  • Core distribution taut-chat and extension taut-pg installed in the same environment

The Postgres database must already exist. taut init initializes the configured schema and tables inside that database; it does not create the database.

The package also supplies Taut's PostgreSQL search provider. It uses only PostgreSQL's built-in tsvector, pg_catalog.simple configuration, GIN, and advisory locks. It never requires CREATE EXTENSION or a separately compiled server extension.

Installation

The core distribution is taut-chat; it still installs the taut command and import package. taut-pg keeps its own distribution name and taut_pg/vX.Y.Z tag stream. Once the first coordinated PyPI release is published:

pipx install taut-chat
pipx inject taut-chat taut-pg

The tag gate reuses the exact wheel and sdist built by canonical Test. It stages them in a draft GitHub Release, publishes them through the taut-pg top-level PyPI Trusted Publisher, verifies filenames and SHA-256 digests, and only then publishes the GitHub Release as immutable.

Configuration

Create .taut.toml in the project root:

version = 1
backend = "postgres"
target = "postgresql://postgres:postgres@127.0.0.1:54329/taut_test"

[backend_options]
schema = "taut_project"

The credentials above are for a disposable local test database. A real target DSN may contain a password and must be treated as a secret. If .taut.toml contains one, add the file to your project's .gitignore, do not commit production credentials, and restrict it to the owner on POSIX systems (for example, chmod 600 .taut.toml). Taut does not interpolate environment variables in this file.

Then initialize Taut normally:

taut init
taut join general

taut init initializes the configured schema and tables; it does not provision the database. taut init --json reports db as the resolved backend display target, and for Postgres created is false because Taut has no public backend creation signal.

TAUT_DB, --db, and db_path= remain filesystem path selectors. Use .taut.toml to select Postgres.

Testing

From the repository root:

uv run ./bin/pytest-pg

That helper starts a temporary Docker Postgres container, runs shared Taut tests against Postgres, runs pg_only extension tests, and removes the container.
