It does happen with some regularity.
At least one large cloud database provider I know of saw this more
than once a month until the mitigations were integrated in the major
version upgrade process.
It is possible that making database upgrades easier via better
automation is what made this turn up more, as now less experienced /
non-DBA types are more comfortable doing the version upgrades, whereas
before it would be something done by a person who can also diagnose it
and manually fix pg_init_privs.
Still it would be nice to have some public support for users of
non-managed PostgreSQL databases as well
