What is TigerFS and how does it work?

TigerFS mounts PostgreSQL databases as filesystems using FUSE (Linux) or NFS (macOS), mapping tables to directories, rows to files, with path-based SQL queries and ACID transactions.

How do you install and use TigerFS?

Run curl -fsSL https://install.tigerfs.io | sh, then tigerfs mount postgres://host/db /mnt/point. Use ls, cat, echo, mv like normal files.

Does TigerFS support Windows or production clusters?

No Windows yet (Linux/macOS only). Production viable for low-throughput; FUSE limits high-IOPS, but ACID shines for concurrent agents.
