LGTM.

Looking at old versions, BackendRun and PostgresMain used to be
declared to return int. Whoever changed that to void evidently
missed updating this comment.
I'd reduce the whole thing to "Doesn't return." If you were feeling
really ambitious you could start plastering pg_attribute_noreturn() on
these functions ... but since that would be placed on the declarations,
a comment here would still be in order probably.
