pgGraph is a PostgreSQL extension (built with pgrx in Rust) that adds graph database capabilities—graph search, traversal, and shortest-path queries—directly on top of existing Postgres data. It is part of the Evokoa/Polygres ecosystem alongside pgContext for vector search, and can be self-hosted or used via their managed cloud.

Use cases

• run graph traversal queries on existing postgres tables
• find shortest paths between entities in a relational database
• model relationships without recursive CTE joins
• add graph database features to postgres without a separate neo4j
• give AI agents graph search over structured data
• combine graph traversal with vector search in one query

When to choose

• your data already lives in Postgres and you want graph queries in place
• you want to avoid operating a separate graph database
• you need hybrid graph + vector retrieval for AI agents
• you prefer self-hosting an extension over a managed service

When to avoid

• you need a full standalone graph database with its own query language
• you require a permissive OSI license for redistribution (license is non-standard)
• you need multi-model graph features beyond traversal such as graph algorithms suites
• you are not on PostgreSQL 14-18
