this depends on what your applications is doing here. if you have a
large list (with the 50 char preview) then your "full view" will likely
be a seperate call (e.g. javascript window, iframe, ...); then you can
use the substring/string manipulation methods of postgres to only get
the data you need. and in the next call get only the full-data that are
requested by the user. but if you are only showing one row and want to
"hide" the full extend there, then you are better of by do you hiding it
in the app.
