	PartialBlock (PartialBlockState state, BlockManager &block_manager, const shared_ptr< BlockHandle > &block_handle)
void	AddUninitializedRegion (const idx_t start, const idx_t end)
	Add regions that need zero-initialization to avoid leaking memory.
virtual void	AddSegmentToTail (ColumnData &data, ColumnSegment &segment, uint32_t offset_in_block)
virtual void	Flush (QueryContext context, const idx_t free_space_left)=0
	Flush the block to disk and zero-initialize any free space and uninitialized regions.

Public Attributes
PartialBlockState	state
	The current state of a partial block.
vector< UninitializedRegion >	uninitialized_regions
	All uninitialized regions on this block, we need to zero-initialize them when flushing.
BlockManager &	block_manager
	The block manager of the partial block manager.
shared_ptr< BlockHandle >	block_handle
	The block handle of the underlying block that this partial block writes to.
