Mount PostgreSQL as a filesystem. Build apps with files, explore databases with ls and cat. A filesystem backed by PostgreSQL, and a filesystem interface to PostgreSQL.
Every file is a real PostgreSQL row. Directories are tables. File contents are columns. Multiple agents and humans can read and write the same files concurrently with full ACID guarantees. No sync protocols. No coordination layer. The filesystem is the API.
TigerFS turns PostgreSQL into a transactional filesystem, either as the backend for your files or as a filesystem over your data. Agents and humans share state through files instead of sync protocols, merge workflows, or custom coordination code.

Incremental View Maintenance (IVM) is a way to make materialized views up-to-date in which only incremental changes are computed and applied on views rather than recomputing the contents from scratch as REFRESH MATERIALIZED VIEW does. IVM can update materialized views more efficiently than recomputation when only small parts of the view are changed.
