Postgres split string dengan tanda kutip ganda ke beberapa baris?

location string mirip dengan array teks. Ubah ke text[] dan tidak menyenangkan:

with my_data(id, location) as (
values 
    (1, '["Humboldt, TN","Medina, TN","Milan, TN"]')
)

select id, unnest(format('{%s}', trim(location, '[]'))::text[]) as location
from my_data

 id |   location   
----+--------------
  1 | Humboldt, TN
  1 | Medina, TN
  1 | Milan, TN
(3 rows)

Atau bahkan lebih sederhana, masukkan string ke jsonb dan gunakan jsonb_array_elements_text() :

with my_data(id, location) as (
values 
    (1, '["Humboldt, TN","Medina, TN","Milan, TN"]')
)

select id, jsonb_array_elements_text(location::jsonb) as location
from my_data
