4. PostgreSQL Extensions

py-pglite supports a growing number of PostgreSQL extensions.

1. Register the Extension:
Add the extension's details to py_pglite/extensions.py.

# py_pglite/extensions.py
SUPPORTED_EXTENSIONS = {
    "pgvector": {"module": "@electric-sql/pglite/vector", "name": "vector"},
    "new_extension": {"module": "npm-package-name", "name": "js_export_name"},
}

2. Add Optional Dependencies:
Add any necessary Python client libraries to pyproject.toml under the [project.optional-dependencies] section.

# pyproject.toml
[project.optional-dependencies]
extensions = [
    "pgvector>=0.4.1",
    "numpy>=1.0.0",
    "new-python-dependency>=1.0.0",
]

3. Add a Test:
Create a new test file in tests/ to validate the extension's functionality. Use the @pytest.mark.extensions marker.

# tests/test_new_extension.py
import pytest

@pytest.mark.extensions
def test_new_extension_feature():
    # ...
