So, you want to create something like:
n312
b943
z338
Correct?
You would probably want to play around with the server side functions in
plpgsql, or even look into something like plperl, plphp, etc. Start off
with getting a function to return you a 4 character string, then when
that appears to be working, look into the plpgsql syntax to figure out
how to check that it's the only one like that otherwise, rerun the
function and return a different string.
Hope that helps get you started in the right direction,
