What client are you using? psql, or something else? In simple
tests I don't see this truncation with psql (8.0.0); I wonder
if your client is truncating the output.

information_schema.views is itself a view; you can see its definition
by executing the following in psql:
\d information_schema.views
The above shows that the view_definition column gets its value from
pg_get_viewdef(). What do the following queries return?
SELECT length(pg_get_viewdef('viewname'::regclass));
SELECT pg_get_viewdef('viewname'::regclass);
