I'm little confused by the convertJsonbValue functon at jsonb_utils.c
Maybe I misunderstood something, so I need help =)
As I can see, the convertJsonbScalar function is used for scalar and
if (IsAJsonbScalar(val) || val->type == jbvBinary)
convertJsonbScalar(buffer, header, val);
jsonb values. But this function doesn't handle the jbvBinary type.
There definitely seems to be an oversight here of some kind. Either
convertJsonbValue() shouldn't be calling convertJsonbScalar() with an
object of type jbvBinary, or convertJsonbScalar() should know how to
handle that case.
Yes, I've just been looking at that. I think this is probably a
hangover from when these routines were recast to some extent. Given
that we're not seeing any errors from it, I'd be inclined to remove
the the "|| val->type == jbvBinary" part. One of the three call sites
to convertJsonbValue asserts that this can't be true, and doing so
doesn't result in a regression failure.
Peter and Teodor, comments?
Thinking about it a bit more, ISTM this should be ok, since we convert a
JsonbValue to Jsonb in a depth-first recursive pattern. We should
certainly add some comments along these lines to explain why the
jbvbinary case shouldn't arise.
