Pull request overview
This PR fixes a bug in ORCA's storage type detection for partitioned tables that contain a mix of foreign and non-foreign partitions. The issue caused incorrect metadata generation when such mixed storage configurations existed, which could lead to problems with scan type selection and query planning.
Changes:
- Added logic to detect and mark mixed storage when foreign partitions are encountered after non-foreign partitions (or vice versa)
- Converted an independent
ifstatement to anelse ifto create a proper conditional chain for storage type transitions - Improved handling of the initial state when the first partition encountered is foreign

…gn partitions The storage type detection logic failed to properly identify mixed storage when foreign and non-foreign partitions coexisted, leading to incorrect metadata that could cause issues with scan type selection and query planning.
