Previously log messages late during shutdown could end up using either another backend's PgBackendStatus (multi user) or segfault (single user) because pgstat_get_my_query_id()'s check for !MyBEEntry didn't filter out use after pgstat_beshutdown_hook(). This became a bug in 4f0b0966c86, but was a bit fishy before. But given there's no known problematic cases before 14, it doesn't seem worth backpatching further. Also fixes a wrong filename in a comment, introduced in e1025044.
