The original partitioning code (f0e44751d717) decided that it didn't
want to bother with adding a "free" routine for PartitionBoundInfo
structs, maybe because it had too many pointers, so there's no way for
RelationBuildPartitionDesc to free everything it allocates anyway. We
could add a couple of pfrees and list_frees here and there, but for the
main thing being leaked we'd need to improve that API.
