From what I can see the sequence name is not changed when you rename a
table
test=# alter table fooseq rename to fooseq1;
ALTER TABLE
test=# \d fooseq1
Table "public.fooseq1"
Column | Type | Modifiers
--------+---------+--------------------------------------------------------
id | integer | not null default
nextval('public.fooseq_id_seq'::text)
so everything should work as expected.
