The original `trap` lines in these scripts are incomplete: in case of any signal, they delete the working directory but let the script run to completion, which is useless because it will only proceed to complain about the working directory being removed. Add `exit` there, with the original exit value (not rm's). Since this is mostly just cosmetic, no backpatch. Discussion: https://postgr.es/m/20220913181002.hzsosy7qkemb7ky7@alvherre.pgsql
