postgresqlfs is a FUSE driver to access PostgreSQL databases as a file system. It exposes the object structure of a PostgreSQL database instance as directories and files that you can operate on using file system tools.
The idea is that you can use this together with Midnight Commander to browse and edit a database in text mode in situations where psql would be to cumbersome but pgAdmin or phpPgAdmin are not available.
Use postgresqlfs --help to get usage information. Usually, it is just
$ postgresqlfs mountpoint
to mount, and
$ fusermount -u mountpoint
to unmount.
You also need access to the /dev/fuse device, which may be tied to
some group membership on your operating system.
