I tested the rebased v18 patch on a clean tree and verified that it
applies cleanly and behaves consistently with previous results.
Cross-session access is correctly blocked with: ERROR: cannot access
temporary relations of other sessions
Index scan paths are also properly restricted, and same-session access
continues to work as expected.
The updated test changes look good. Everything works as expected, +1
from my side.
