Introducing pgledger, a financial ledger implementation built entirely in PostgreSQL. This innovative solution allows for transactional and atomic ledger updates within the same database transaction as other application data. By leveraging PostgreSQL's capabilities, pgledger eliminates the need for external ledger services or complex integration, making it an attractive option for startups and small companies. With its pure SQL implementation, pgledger is language- and framework-agnostic, providing a flexible and portable solution for managing financial data. The project is currently in development, with testing underway in Go, and feedback is welcome from those who work with ledgers. Check out pgledger on GitHub and explore its potential to simplify your financial data management.
