No. You are supposed to be someone who knows better --- and if you
don't, you should not be running with write privileges on those
files. pg_dump has absolutely no way to know that that particular
output file is something important. Even if we tried to put that
knowledge into it, there are tiny variations of this case that
would still break, such as
./pg_dump ... >postgres
or for that matter
echo oops >postgres
There is no point in trying to prevent pg_dump from overwriting a
postgres executable when there are thousands of other ways to do
that, if you're foolish enough to not be more careful with file
permissions.
