Create array of data from JSONB in PG 9.5

[Arup Rakshit <ar@xxxxxxx>]

Hi,

I wrote the below SQL which works and give me what I want, but it doesn’t work in 9.5 version. I wrote this query in PG 10. I want to change it so that I can run it on 9.5 as production using 9.5 version. I need help on this.

SELECT DISTINCT
	ARRAY [jsonb_array_elements(data) ->> 'group', jsonb_array_elements(jsonb_array_elements(data) -> 'properties') ->> 'name']
FROM
	"vessels"
WHERE
	"vessels"."deleted_at" IS NULL
	AND "vessels"."company_id" = '7d105acd-be5a-4225-a2db-b549105e4172';


When I ran the same query to production I get error:

ERROR:  set-valued function called in context that cannot accept a set


Thanks,
