heap_force_common() tracked the current position in the caller-supplied tid[] using OffsetNumber, which is only 16 bits wide, so when the array held more than 65535 entries, the updated index wrapped around and the outer loop never reached the exit condition. A SQL call with a sufficiently large TID array would then run until interrupted. Fix by tracking the tid[] position using int instead of OffsetNumber. A regress case based on the report is included.
