PostgreSQL Transactional Tests

pg-transactional-tests is a utility library designed to simplify database testing by wrapping each test in a PostgreSQL transaction. It currently stands at version 1.2.0, with a stable release cadence implied by its versioning and active development. The library patches the `pg` package to automatically initiate a transaction before a test, and then roll it back afterward, ensuring a clean database state for every test run without the overhead of clearing tables. A key differentiator is its compatibility with many popular ORMs like Sequelize, TypeORM, MikroORM, Objection, and Knex, which all build upon the `pg` driver. It also intelligently handles nested transactions using savepoints and supports parallel testing across multiple databases by tracking transaction state per connection. A significant limitation is its incompatibility with Prisma, due to Prisma's distinct database interaction model. This approach vastly accelerates test suites and reduces boilerplate for database setup and teardown.
