Postgres JSONb ke XML dengan tag_name dan tag_value

Membangun solusi @Georges Martin, saya tidak akan menggunakan gabungan lateral dan klausa pengelompokan, melainkan hanya subquery bersarang:

SELECT XMLELEMENT(
  NAME "Company", 
  XMLATTRIBUTES(id AS id, field1 AS field), 
  (SELECT XMLAGG(
    XMLELEMENT(
      NAME "companyTag", 
      XMLATTRIBUTES(
        attr.key AS "tagName", 
        attr.value AS "tagValue"
      )
    )
  ) FROM JSONB_EACH_TEXT(attributes) AS attr)
) FROM comp_emp;
