Postgresql SQL output set column width

Hi

I have some SQL that when it outputs to a file I need to have it set the column to a shorter width.


select app, note, message from abc


output is currently

app                         note                                     message
-----------------------    -----------------------------         ------------------------------------
aaksssjjdjddjdjd    dsssss sssssd ddddd        my message is this long



But needs to be

app                note               message
--------             ------------         ---------------
aakss             dsssss s         my messa


Not sure there is a way to limit the column width on output from psql


Thanks

Mike
