postgresql - Get table and column "owning" a sequence

Question

I can run the following line:

ALTER SEQUENCE seqName OWNED BY table.id;

How can I get the 'owner' set by OWNED BY for a sequence (in this case: table.id)?

Answer 1

You may use following query:

select s.relname as seq, n.nspname as sch, t.relname as tab, a.attname as col
from pg_class s
  join pg_depend d on d.objid=s.oid and d.classid='pg_class'::regclass and d.refclassid='pg_class'::regclass
  join pg_class t on t.oid=d.refobjid
  join pg_namespace n on n.oid=t.relnamespace
  join pg_attribute a on a.attrelid=t.oid and a.attnum=d.refobjsubid
where s.relkind='S' and d.deptype='a'

It returns all sequences with owner information. Just filter them in WHERE clause and that's it.
