Re: More jsonpath methods: translate, split, join - Mailing list pgsql-hackers

Hello

+                /* Validate target is an array */
+                if (JsonbType(jb) != jbvArray)
+                {
+                    RETURN_ERROR(ereport(ERROR,
+                                         (errcode(ERRCODE_INVALID_PARAMETER_VALUE),
+                                          errmsg("jsonpath item method .join() can only be applied
to an array"))));

Other methods seem to use ERRCODE_SQL_JSON_ARRAY_NOT_FOUND

+                else
+                {
+                    /* Recursive Tree (jbvArray) */
+                    for (int i = 0; i < jb->val.array.nElems; i++)

Isn't this branch unreachable?
