OK, in that case it's definitely all the temporary data that gets created
that is the problem. I've not examined your patch in great detail but
it looks plausible for fixing that.
I think that RelationBuildPartitionDesc could use some additional cleanup
or at least better commenting. In particular, it's neither documented nor
obvious to the naked eye why rel->rd_partdesc mustn't get set till the
very end. As the complainant, I'm willing to go fix that, but do you want
to push your patch first so it doesn't get broken? Or I could include
your patch in the cleanup.
