I would rather recommend not deinstalling 7.3.4!

You can compile and install 7.1.3 into a temporary directory and
listening to a different port.

     ./configure --prefix=/usr/local/pg71_temp --with-pgport=5439
     make
     make install

Now you restore the old installations data directory into the directory
/usr/local/pg71_temp/data and start the 7.1.3 postmaster.

You now use the 7.3.4 pg_dumpall command to dump the contents

     PGPORT=5439
     export PGPORT
     pg_dumpall >(wherever_you_want_the_dumpfile)

You can stop the 7.1.3 postmaster now and proceed with reloading the
dump into your 7.3.4 installation

     unset PGPORT
     psql <(that_darn_dumpfile)
