+// This test documents the critical bug where the existing FDW binary was deleted
+// before verifying that the new binary could be successfully extracted.
+//
+// Bug Scenario (BEFORE FIX):
+// 1. User has working FDW v1.0 installed
+// 2. Upgrade to v2.0 begins
+// 3. os.Remove() deletes the v1.0 binary (line 70 in fdw.go)
+// 4. Ungzip() attempts to extract v2.0 binary (line 72)
+// 5. If ungzip fails (corrupt download, disk full, etc.):
+//    - Old v1.0 binary is GONE (deleted in step 3)
+//    - New v2.0 binary FAILED to install (step 4)
+//    - System is now BROKEN with no FDW at all
+//
+// This test simulates the old buggy behavior for documentation purposes.
+// It is skipped because it will always fail (it simulates the bug itself).
+// The fix ensures this scenario can never happen in the actual code.
