GitHub user Kxrma47 added a comment to the discussion: Apache Cloudberry through ODBC into Apache Arrow (adbcBridge 0.1.0) — is multi-argument unnest a safe bulk-ingest path on Cloudberry?
The probe shows that the PostgreSQL-compatible path works today, but I would not make the banner the compatibility contract. Enable it through a capability test run in a rolled-back transaction, and retain the multi-row fallback. The probe should include unequal-length arrays because PostgreSQL pads shorter arrays with NULL, plus a distributed table and the AO storage modes you already test. That protects the bridge if planner or fork behavior changes without changing the version banner. PostgreSQL documents multi-array UNNEST here: https://www.postgresql.org/docs/14/functions-array.html. Until Cloudberry documents an equivalent stability guarantee, capability detection is safer than a permanent fork allow-list.
