Summary

Lead is a PostgreSQL full-text search extension designed to provide TIN-compatible functionality for testing, CI, development, and staging environments where the faster TIN extension may not be available. It supports the same SQL statements, TINQL queries, tokenization behavior, BM25 scoring, hit highlighting, transactional writes, snapshot isolation, rollback handling, and restart durability as TIN, ensuring that search behavior remains consistent across environments. Unlike TIN, however, Lead intentionally performs every search as a full table scan and is not intended for production-scale workloads, with large datasets requiring minutes per query rather than milliseconds. The developers recommend using Lead with CI datasets of only a few megabytes while deploying TIN for production search applications, and invite user feedback on compatibility needs.
