I am curious, why would a query on a parent table, A, put a lock on a child table, B? If the query doesn't touch B or any of its children, why would PostgreSQL care what happens to the child table during its query?

No, but it certainly locks the child table ... and queries on A are
going to try to scan all three tables.
