As far as I know (as this is the behavior in debian stable)
the ubuntu people use libgettext and not libreadline.

You can force it to use libreadline by using LD_PRELOAD.  I reccomend 
that you do I did this by editing /usr/bin/psql which is a perl script

In any case linux doesn't propogate SIG_WINCH to the other processes
that are using the pty so even if you are using readline you have to 
force this by resizing the window again after exiting the pager, and
then press ctrl-l to clear the screen.
