I'm new here so someone more experienced would have to weigh in,
but I would wonder a couple of things:

a. whether a braced struct assignment is supported in every  C compiler that PostgreSQL still intends to support

b. whether such a struct assignment is guaranteed to initialize  padding spaces as well as declared fields (in all
supported C versions/compilers).
 

It's possible that memset() would be more convincing.
