It looks like the tests will need to skip CockroachDB. |

@nickcruess-soda @jackc I seem to be late to the game but this will always return nil, since Unmarshal(..) expects the variable to be of slice, struct or string. https://pkg.go.dev/encoding/xml#Unmarshal
Unmarshal parses the XML-encoded data and stores the result in the value pointed to by v,
which must be an arbitrary struct, slice, or string.
Well-formed data that does not fit into v is discarded.

Returning the bytes seem to be the better choice.
Am I missing something?

We have a need for the XML column type but observed that it isn't currently supported. I've taken the JSONCodec as a starting point and adapted it for XML. They turned out to be quite similar. I left in some of the issue-referencing comments from the JSONCodec which seemed relevant here as well, such as the one explaining the
driver.Valuervsxml.Marshalerordering inPlanEncode.While I was at it I also noticed some unused code related to the JSONCodec (
scanPlanJSONToBytesScanner), which I removed in the second commit. Happy to drop that if this isn't the place/time for it.
