you can just add /e to the starting command line in the registry to make it run as Administrator:

If you are using linux you just need to remove the symlinks from the previous versions and point to the version that you are using like this:

locate pg_dump

sudo rm /usr/bin/pg_dump
sudo rm /usr/bin/pg_dumpall
sudo rm /usr/bin/pg_dropcluster
sudo ln -s /usr/lib/postgresql/9.3/bin/pg_dump /usr/bin/
sudo ln -s /usr/lib/postgresql/9.3/bin/pg_dumpall /usr/bin/
sudo ln -s /usr/lib/postgresql/9.3/bin/pg_restore /usr/bin/
sudo rm /usr/bin/pg_restore
sudo ln -s /usr/lib/postgresql/9.3/bin/pg_restore /usr/bin/
