select * from a subquery selects all columns for all tables in the subquery

What happened?

When selecting * from a subquery, the generated query selects all columns from all tables referenced in the subquery, not all fields selected by the subquery.

With the example provided below, the following query is generated:

SELECT t.id, authors.id, name, bio FROM (select id from authors) t

The generated query should be:

SELECT t.id FROM (select id from authors) t

If you modify the query to be:

SELECT t.* FROM (select id from authors) t;

then the generated query is correct.

Relevant log output

Database schema

CREATE TABLE authors (
  id   BIGSERIAL PRIMARY KEY,
