pg_graph provides a way of handling graph-based data structures within the relational database PostgreSQL. In particular, it provides a convenient means of inserting graphs as BLOB-like objects in the RDBMS. Primarily, however, it provides a mechanism for indexing the graphs to provide efficient means to perform nearest-neighbor queries over collections of graphs.
