FWIW, I encountered this behavior as well (with pg_stat):
https://www.postgresql.org/message-id/18158-88f667028dbc7e7b@postgresql.org
and proposed a way to detect such shutdowns for a discussion:
https://www.postgresql.org/message-id/flat/290b9ae3-98a2-0896-a957-18d3b60b6260%40gmail.com
where Shveta referenced a previous thread started by Tom Lane:
https://www.postgresql.org/message-id/flat/2366244(dot)1651681550(at)sss(dot)pgh(dot)pa(dot)us
What do you think about leaving postmaster.pid on disk in case of an
abnormal shutdown?

Alexander
