Indeed that was wrong.

This looks better for the umask setting, still it could be more
simple.

 #include <sys/time.h>
-
+#include "common/file_perm.h"
 #include "lib/stringinfo.h"
Nit: it is better for readability to keep an empty line between the
system includes and the Postgres ones.

A second thing, more important, is that you can reset umask just after
opening the file, as attached.  This way there is no need to reset the
umask in all the code paths leaving update_metainfo_datafile().  Does
that look fine to you?
