Shout out to AndrewSN for this one (although I was almost there when he
pasted it ;)):

SELECT c1.relname AS sequencename, n.nspname AS schema, 
       c2.relname AS tablename, a.attname AS columnname
   FROM pg_class c1
   JOIN pg_depend d ON (d.objid=c1.oid)
   JOIN pg_class c2 ON (d.refobjid=c2.oid)
   JOIN pg_attribute a ON (a.attrelid=c2.oid AND a.attnum=d.refobjsubid)
   JOIN pg_namespace n ON (n.oid=c2.relnamespace)
WHERE c1.relkind='S'
AND d.classid='pg_class'::regclass
AND d.refclassid='pg_class'::regclass
AND d.refobjsubid > 0
AND d.deptype='a';

sequencename | schema | tablename | columnname 
- --------------+--------+-----------+------------
 foo_id_seq   | public | foo       | id
(1 row)

- From there, scripting should be easy.

Sincerely,
