inspect your cast functions with:
create view showcasts as select t.typname as source, t1.typname as target, p.proname as function, (select case when
c.castcontext= 'e' then 'Must use Explicit Cast' else ( select case when c.castcontext = 'i' then
'Implicitcast for expressions and assignments' else 'Implicit cast only for assignments' end)
end) as casttype from pg_cast c, pg_type t, pg_type t1, pg_proc p where c.castsource = t.oid and c.casttarget =
t1.oidand c.castfunc = p.oid;
Un saludo.

You probably want to use to_char to convert the numeric value to a string
which can be displayed.
