At one time there were C compilers that only accepted the former syntax.
But we have already occurrences of the latter in our tree, and no one
has complained, so I think that's a dead issue by now.

I do agree with the idea that we should use the * notation in cases where
the reader might otherwise think that a plain function was being invoked,
ie I don't like
some_function_pointer(args);

Even if the compiler isn't confused, readers might be.  But in the case of
structname->pointerfield(args);

it's impossible to read that as a plain function call, so I'm okay with
dropping the extra punctuation there.
        regards, tom lane
