Thanks for taking care of this!

I found another bug in error handling of whole-row references in join
pushdown; conversion_error_callback fails to take into account that
get_relid_attribute_name(Oid relid, AttrNumber attnum) can't handle
whole-row references (ie, attnum=0), in which case that would cause
cache lookup errors.  Attached is a small patch to address this issue.

Best regards,
