I thought that you would have changed that as well, but that's not
completely complete... In my opinion, HEAD is wrong in using the same
RangeVar for error reporting for a parent table and its partitions, so
that's not completely the fault of your patch. But I think that as
this patch makes vacuum routines smarter, you should create a new
RangeVar using makeRangeVar as you hold the OID of the child partition
in this code path. This would allow error reports to actually use the
data of the partition saved here instead of the parent data.
The rest looks fine to me.
