Pull request overview
This PR fixes an assertion failure in the GPORCA optimizer by implementing the EpetRewindability() method for CPhysicalDynamicTableScan. The missing implementation prevented the optimizer from properly validating whether rewindability requirements were satisfied, causing crashes during plan context validation.
Key changes:
- Implements
EpetRewindability()method to check compatibility between required and derived rewindability properties - Adds method declaration to the class header with appropriate documentation
