GQL and SQL/PGQ: Theoretical Models and Expressive Power
Summary: Introduce Core PGQ and Core GQL formal models capturing SQL/PGQ vs GQL and contrasting PGQ's bottom-up with GQL's pipelined evaluation. Theoretically pinpoint expressiveness gaps that necessitate language extensions and empirically show standard workarounds are impractical. (summarized by gpt-5-mini on Feb 09 2026)
