Since pg is tested directly using the physical plan, the executed SQL includes a complete physical plan, and the abbreviated physical plan is:
WORKTABLESCAN{targetlist=[TargetEntry{targetexpr=CONST{constvalue ="61",consttype ="int4"},targetresname="Z",resjunk=False}],qual=[],wtParam = 59}

Bug reference: 17998
Logged by: Jerry

Description:
I developed a fuzzing tool that skips the optimizer and directly uses the
correct physical plan to fuzz postgres, and found a crash caused by
executing WorkTableScan.
For detailed steps to reproduce, see the
