## What it is
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
