I see what you mean. The attached patch fixes this, as well as
adjusting the error message. I didn't see any other cases.
I thought maybe the schema wasn't mentioned because the table.column
defaults to the sequence's schema, but it does not --- you have to
specify the column's schema if would not be normally be found via
search_path:
CREATE SCHEMA zz;
SET search_path = zz, public;
CREATE TABLE zz.test (x INT);
CREATE SEQUENCE zz.ss;
ALTER SEQUENCE zz.ss OWNED BY test.x;
SET search_path = public, zz;
ALTER SEQUENCE zz.ss OWNED BY test.x;
SET search_path = public;
ALTER SEQUENCE zz.ss OWNED BY test.x;
--> ERROR: relation "test" does not exist
ALTER SEQUENCE zz.ss OWNED BY zz.test.x;
