function 'IS JSON ARRAY' not identified
Table 'Jsondata2' contains 2 columns, 'id' and 'data'. 'data' is of jsonb type.
When running query
select d.data - 'keya' || jsonb_build_object('keya', jsonb_array_elements(d.data::jsonb-> 'keya'))
from "Jsondata2" as d
where jsonb_exists(d.data '$.keya') and d.data->'keya' is not null and d.data->'keya' IS JSON ARRAY;
I get the error message:
ERROR: syntax error at or near "JSON" LINE 3: ... d.data->'keya' is not null and d.data->'keya' IS JSON ARRAY... ^

Tom,
thanks for taking a look at this so quickly. Shame homebrew is so behind, but this is a kind of a relief.
Regards,
Antonio
