Una query che elenca i tag e ha una colonna di tutti i loro gruppi di tag associati?

Ciò dovrebbe essere possibile con qualcosa di simile a questo:

```sql
SELECT 
    t.name AS "Tag",
    STRING_AGG(tg.name, ', ' ORDER BY tg.name) AS "Gruppi di tag"
FROM tags t
  JOIN tag_group_memberships tgm ON tgm.tag_id = t.id
  JOIN tag_groups tg ON tg.id = tgm.tag_group_id
GROUP BY t.name

```
