Here's a thought. in pushJsonbValue() the value pushed is called
scalarVal, and in all our regression tests it is in fact scalar.
However, the Asserts inside the function tell a different story:
case WJB_VALUE: Assert(IsAJsonbScalar(scalarVal) || scalarVal->type == jbvBinary);
appendValue(*pstate, scalarVal); break; case WJB_ELEM:
Assert(IsAJsonbScalar(scalarVal)|| scalarVal->type == jbvBinary); appendElement(*pstate,
scalarVal); break;
and indeed it turns out that your delete example does push a value with
jbvBinary, thus triggering the problem. So, could we deal with that, by,
say, setting up an iterator for the binary datum and just pushing all of
its values?
