Better Exception Message for Required Length in HTTP POST Query

Official CH changelog text
Better exception message when length is required in HTTP POST query. #9453 (alexey-milovidov)
Improved exception messages for missing Content-Length in HTTP POST queries.

Why it matters

Enhances user experience by providing clearer and more informative error messages when the HTTP POST query to ClickHouse lacks the required Content-Length header, helping diagnose request issues faster.

How to use it

No special configuration needed. When sending HTTP POST requests to ClickHouse, ensure the Content-Length header is included. If it is missing, the system will now return a better, more descriptive exception message.
