Yes. The above is good style because it ensures that the variable
you're assigning the pointer to is the right type to match the sizeof
computation. In C++ you'd use operator new instead and still have that
type-check without the cast, but indeed we are not writing C++ here.
The *real* bug in the quoted code is that it's using malloc. There are
a few places in PG where it's appropriate to use malloc not palloc, but
pretty darn few.
