In this query:

select n.nspname as table_schema, c.relname as table_name,
a.attname as column_name
from pg_catalog.pg_attribute a
join pg_catalog.pg_class c on ( a.attrelid = c.oid)
join pg_catalog.pg_namespace n on (c.relnamespace = n.oid)
where c.relkind in ('r','v') and a.attnum > 0
and n.nspname not in ('pg_catalog','information_schema')
order by 1,2,3

change the following:
where c.relkind in ('r','v')
to
where c.relkind = 'r'

Cheers,

Andy
