Re: Weird special case in jsonb_concat()

Hi,
w.r.t. the patch,

+select '[3]'::jsonb || '{}'::jsonb;
+ ?column?
+----------
+ [3, {}]
+(1 row)
+
+select '3'::jsonb || '[]'::jsonb;

Should cases where the empty array precedes non-empty jsonb be added ?

select '[]'::jsonb || '3'::jsonb;
select '{}'::jsonb || '[3]'::jsonb;

Cheers
