This module does a check that is not needed.

clickhouse-go/lib/column/date_helpers.go

Line 45 in 7134777

func (e *DateOverflowError) Error() string {

Clickhouse allows insertion of data earlier than 1900. A conversion to the minimum date for the field type is performed.

Moreover, a similar check is not performed for the field type Date.
