Added support for reading Date values from text where month and/or day can be specified using a single digit instead of two digits.
Why it matters
This feature was created to improve the flexibility and robustness of parsing Date values by allowing input dates to be in a more lenient format. It solves the problem of strict parsing requiring two-digit month and day, which can cause errors or require data preprocessing when dates are formatted with single-digit months or days. This increases usability for users importing or working with diverse date formats.How to use it
When reading Date values from text input, you can now provide dates where the month and/or day of the month is represented as a single digit (for example, 2024-6-7 instead of 2024-06-07). The ClickHouse parser automatically recognizes and correctly reads these dates without errors or additional configuration.
