PostgreSQL 19 connects the dots with standardized graph queries

PostgreSQL 19 is scheduled to be released from late September to early October 2026. It will integrate standardized graph query syntax based on the SQL 2023 standard (SQL/PGQ). This feature was developed jointly by main contributors to PostgreSQL and members of the SQL Standards Committee, and it is heavily influenced by the open-source language OpenCypher. The current implementation can efficiently handle node and edge queries, but performance optimization requires further work with index plugins. Additionally, some syntax features need to be added to significantly replace dedicated graph databases.
