Hello, I think the problem here is that the %s is not the file name, but
the string from strerror.  So the lack of quotes there would seem to be
correct.  The real problem is that the file name isn't mentioned in the
error message.  A secondary issue might be that instead of using %s for
strerror(), maybe they should be using %m.

Maybe we should do something like

		pg_fatal("could not open "%s" file: %m", map_file_path);
