static DUCKDB_API BaseStatistics	CreateUnknown (LogicalType type)
	Unknown statistics - i.e. "has_unicode" is true, "max_string_length" is unknown, "min" is \0, max is \xFF.

static DUCKDB_API BaseStatistics	CreateEmpty (LogicalType type)
	Empty statistics - i.e. "has_unicode" is false, "max_string_length" is 0, "min" is \xFF, max is \x00.

static DUCKDB_API bool	HasMaxStringLength (const BaseStatistics &stats)
	Whether or not the statistics have a maximum string length defined.

static DUCKDB_API uint32_t	MaxStringLength (const BaseStatistics &stats)
	Returns the maximum string length, or throws an exception if !HasMaxStringLength()

static DUCKDB_API bool	CanContainUnicode (const BaseStatistics &stats)
	Whether or not the strings can contain unicode.

static DUCKDB_API string	Min (const BaseStatistics &stats)
	Returns the min value (up to a length of StringStatsData::MAX_STRING_MINMAX_SIZE)

static DUCKDB_API string	Max (const BaseStatistics &stats)
	Returns the max value (up to a length of StringStatsData::MAX_STRING_MINMAX_SIZE)

static DUCKDB_API void	ResetMaxStringLength (BaseStatistics &stats)
	Resets the max string length so HasMaxStringLength() is false.

static DUCKDB_API void	SetMaxStringLength (BaseStatistics &stats, uint32_t length)
	Sets the max string length.

static DUCKDB_API void	SetContainsUnicode (BaseStatistics &stats)
	FIXME: make this part of Set on statistics.

static DUCKDB_API FilterPropagateResult	CheckZonemap (const_data_ptr_t min_data, idx_t min_len, const_data_ptr_t max_data, idx_t max_len, ExpressionType comparison_type, const string &value)

static DUCKDB_API void	Update (BaseStatistics &stats, const string_t &value)

static DUCKDB_API void	SetMin (BaseStatistics &stats, const string_t &value)

static DUCKDB_API void	SetMax (BaseStatistics &stats, const string_t &value)
