Upgrade Guide

AgensGraph is a multi-model graph database built on PostgreSQL, designed for complex modern data environments. It supports both relational and graph data models in a single system, allowing seamless integration of legacy relational structures with flexible graph models. Supporting Ansi-SQL and Open Cypher, and partially aligned with the emerging ISO/IEC Graph Query Language (GQL) standard, it enables combining SQL and Cypher in a single query. Optimized for managing highly connected graph data, AgensGraph delivers enterprise-ready features including ACID transactions, multi-version concurrency control, stored procedures, triggers, constraints, advanced monitoring, and JSON support, while also benefiting from the PostgreSQL ecosystem and extensions such as PostGIS.
