RedHat 7.3 I guess you mean?

What directory you are in has nothing to do with which copy of a program you 
will run. There is a utility called "which" to help you: "which pg_dump".
Almost certainly what you want to do is:
  /usr/local/pgsql/bin/pg_dump -h ...

You probably want to get a book on unix/linux and read up about the various 
search paths.
