Dear Aritz
It is possible to take psi k ^2 using PWSCF

What you need to do is  1)  run the scf run
                        2)  set up an input file for the executable pp.x
   An example is given below:
prefix = 'WC',
outdir = '/home/tijuthomas/PWSCF_2.0.1/6HEnergySurfaceSF1/tmpSF1minbands//',
filplot = 'SF1AvgKchdensin',
plot_num = 7 ,
kpoint = 11,
kband = 49 ,


You should know the k point index at which pisk^2 needs to be plotted and
the band index in which you are interested, just in case your scf run was
done using a monkhorst pack mesh which was automatically generated, hence
the k point that interests you did not feature in the k point mesh
generated, please rerun the file using a specification of k points that
suits you- like the one done in a band structure calculation, since you
are mentioning the kpoints in this case, you are sure to get the k point
of interest in the list!! also note the label of the k point- it is that
which has to be supplied for kpoint.

Please feel free to write to me if you still have trouble,

The kband can be easily decided I suppose,  the plot num option should be
set correctly, please note this apart you can also plot the local ionic
potential etc in the 3-D form whch is compatible with the xcrysden
software. The prefix is the prefix that you give for your pw input file.
