Hello,
Commit 51ff46de29f67d73549b2858f57e77ada8513369 (backported all the way back to v12) added a new member to `ResultRelInfo` struct. This can potentially cause ABI breakage for the extensions that allocate the struct and pass it down to the PG code. The previously built extensions may allocate a shorter struct, while the new PG code would expect a larger struct, thus overwriting some memory unintentionally.
A better approach may have been what Tom did in 8cd190e13a22dab12e86f7f1b59de6b9b128c784, but I understand it might be too late to change this since the releases are already tagged. Nevertheless, I thought of bringing it up if others have different views.
Thanks,
Pavan
