pg_ladybug
A PostgreSQL extension that embeds the LadybugDB engine to run Cypher queries from SQL. Registered Postgres tables act as node and relationship labels, and Ladybug's planner rewrites each pattern into a single SQL join executed natively by Postgres; Cypher can also run against Ladybug-native tables stored in the data directory.
