如何通过“|”连接 json 数组值？

Question

我有 jsonb 格式的列。列名是“column1”，table 是“table1”

{
.....
"source_types": {
  "source_type_os": [ ,

      1,3,5
    ],
   ....
  },
  ....
}

我可以像“[1,3,5]”这样的数组字符串，但我需要得到像 1|3|5

这样的东西

我试过这个代码

select ....
       t1.column1::jsonb #>>'{source_types,source_type_os}' as "test", <--here the problem
       ....
from table1 t1
where ....;

Answer 1

select ....
       string_agg(c.col, '|') as "test"
  from table1 as t1
 cross join lateral jsonb_array_elements_text(t1.column1::jsonb #>>'{source_types,source_type_os}') as c(col)
 group by t1

Answer 2

select ....
       replace(trim(both '[]' from t1.column1::jsonb #>>'{source_types,source_type_os}'),',','|') as "test",
       ....
from table1 t1
where ....;
