What is TigerFS and how do you install it?

TigerFS is an open-source FUSE/NFS filesystem that mounts PostgreSQL databases as directories. Install via Cargo (it's Rust), connect to your Postgres, mount with fuse or nfsd.

Does TigerFS work with large PostgreSQL databases?

Best for small-to-medium datasets fitting memory; scales via Postgres but FUSE overhead hits big ls/grep ops. Test your workload.

Can AI agents use TigerFS for shared state?

Yes — file moves signal tasks (todo/doing/done), ACID ensures no lost updates in multi-agent setups.
