On the assumption that the sort of dependence you're looking for is one where
a column has a default value of nextval('some_sequence'), this worked for me:
select
attrelid::regclass || '.' || attname,
adsrc
from
pg_attrdef ad
join pg_attribute pa
on (ad.adrelid = pa.attrelid and pa.attnum = ad.adnum)
where
adsrc ~* 'nextval'
