Both {min,max}_partition_size currently work with 0 with the default
balanced partitioning, and likely someone uses it.
And both values make some sense:
min_partition_size=0 -> there is no minimal partition size
max_partition_size=0 -> put every function into its own partition
Both seem to be an expected outcome of approaching/reaching 0.
