PostgreSQL Git Foreign Data Wrapper

git_fdw is a Git Foreign Data Wrapper for PostgreSQL written in C.

It is making use of libgit2.

INSTALLATION

Prerequisites

• libgit2-dev (supports up to v0.27)
• PostgreSQL 9.4+

Building the extension

With PGXN

Simply run

pgxn install git_fdw

From source

Building git_fdw is as simple as

make

and installing it only requires oneself to

make install

Configuring the Foreign Data Wrapper

Now you can start setting up your environment to access git repositories:

λ psql
psql (9.4.1)
Type "help" for help.

franck=# CREATE EXTENSION git_fdw;
CREATE EXTENSION

franck=# CREATE SERVER git_fdw_server FOREIGN DATA WRAPPER git_fdw;
CREATE SERVER

franck=# CREATE FOREIGN TABLE
    rails_repository (
        sha1          text,
        message       text,
        name          text,
        email         text,
        commit_date   timestamp with time zone,
        insertions    int,
        deletions     int,
        files_changed int
    )
    SERVER git_fdw_server
    OPTIONS (
        path   '/home/franck/rails.git',
        branch 'refs/heads/master'
    );
CREATE FOREIGN TABLE

franck=# SELECT message, name FROM rails_repository LIMIT 10;
                         message                          |          name

It is not possible to access multiple repositories through the same foreign table. We suggest the usage of views if this is something that needs to be achieved.

CONFIGURATION

Server

There are no options that can be passed to a git_fdw server.

Foreign Table

The possible options are:

• path: The path of the git repository;
• branch: The branch to be used.

Note on Patches/Pull Requests

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don't break it in a future version unintentionally.
• Commit, do not mess with version or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.
