Measured SQL performance findings — query plans, index trade-offs, and planner behavior, benchmarked at real data scales.https://exobench.aihttps://exobench.ai/blog/pg19-graph-queries-part-1https://exobench.ai/blog/pg19-graph-queries-part-1Postgres 19 adds SQL/PGQ graph queries. Measured against a PostgreSQL 19beta1 build, the fixed-depth graph query compiles to the exact same plan as a hand-written join, and the variable-depth traversal that graph databases were built for still falls to a recursive CTE. Apache AGE runs the same indexed traversal under a Cypher wrapper.
