I like the diffstat.

The only difference between the old and new code is that the old code
passes NULL as 'extra_have' and the new code passes &data->extra_have.

That means this populates the data->extra_have oid_array.  Does it
matter?

not a new problem, just curious: Does this leak tmp_refs?

Same question as the other caller about whether we mind getting
extra_have populated.
