Try this query
select a.relname as base,a.relkind
from
pg_class a
join pg_depend d on (a.oid = d.refobjid)
join pg_class c on (d.classid = c.oid)
join pg_rewrite r on (objid = r.oid)
join pg_class v on (ev_class = v.oid)
where a.relkind in('r', 'v')
and a.relname <> v.relname
and v.relname='YOUR VIEW NAME HERE'
order by 1

I have been thinking the problem through again, and I think I am able to
solve the problem if I just know which tables the view is using.
But how do I get this information from the pg_depend table?
