PG_OBSSCANINFO

PG_OBSSCANINFO defines OBS runtime information scanned in cluster acceleration scenarios. (Due to specification changes, the current version no longer supports the current feature. Do not use this feature.) Each record corresponds to a piece of runtime information of a foreign table on OBS in a query. (The current feature is a lab feature. Contact Huawei technical support before using it.)
