Fix copy-paste error in datum_to_jsonb_internal()
Commit 3c152a27b06 mistakenly repeated JSONTYPE_JSON in a condition,
omitting JSONTYPE_CAST. As a result, datum_to_jsonb_internal() failed
to reject inputs that were casts (e.g., from an enum to json as in the
example below) when used as keys in JSON constructors.
This led to a crash in cases like:
SELECT JSON_OBJECT('happy'::mood: '123'::jsonb);
where 'happy'::mood is implicitly cast to json. The missing check
meant such casted values weren’t properly rejected as invalid
(non-scalar) JSON keys.
