Linux – pg_dump not working – do I need to change order of $PATH

I'm trying to set the $PATH to pick up the latest version of pg_dump as I'm currently getting a mismatch error while doing a migrate in my Rails app (I recently changed the schema type to SQL).

I have added a new file in /etc/profile.d called pg_dump.sh, and inside that put:

PG_DUMP=/usr/pgsql-9.1
export PG_DUMP
PATH=$PATH:$PG_DUMP/bin
export PATH

On looking at echo $PATH, I get:

/usr/local/rvm/gems/ruby-1.9.3-p194/bin:/usr/local/rvm/gems/ruby-1.9.3-p194@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p194/bin:/usr/local/rvm/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/pgsql-9.1/bin:/root/bin

And I still get the error.

Do I need to change the order? If so any ideas how?

Output of 'ls /usr/pgsql-9.1/bin':

And output of 'which pg_dump':

/usr/bin/pg_dump
