Filesystem Foreign Data Wrapper

Exposes the filesystem to PostgreSQL, allowing files and directories to be read via SQL commands.

Install

First, install the required python modules:

pip install -r requirements.txt
pip install .

Next, install the extension files into PostgreSQL's extension directory:

make install

Finally, from a PostgreSQL shell, install the extension:

CREATE EXTENSION multicorn;
CREATE EXTENSION filesystem_fdw;
