Re: Convert numeric to money

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.
