I think what you are showing here is that you ran this command in the
installation's bin directory, and where you write "-f postgres",
that caused pg_dump to overwrite the postgres executable.

Don't do that. Generally speaking, you don't want installed files to
be writable at all by ordinary user accounts ... but if they are,
for heaven's sake don't cd into those directories before doing work.
You're just setting yourself up for trouble.
