PostgreSQL ctid type confusion in selectivity estimator discloses derivative of arbitrary read

Type confusion regarding input of PostgreSQL ctid data type selectivity estimator allows an object creator to view a calculation derived from the value of an arbitrary 4-byte span of memory, via a chosen non-ctid input.  While the calculation loses precision, substantial memory value recovery appears possible.  Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.
