PostgreSQL Error 2201G: Invalid Width Bucket Argument
Description
Error 2201G indicates that an invalid argument was provided to the `width_bucket()` function in PostgreSQL. This typically occurs when the function's parameters, such as the minimum value, maximum value, or number of buckets, do not meet its operational requirements.
Error Message
invalid argument for width bucket function
Known Causes
4 known causesInvalid Range Definition
The `min_value` argument is greater than the `max_value` argument, which violates the function's requirement for a valid, increasing range.
Non-Positive Bucket Count
The `num_buckets` argument is provided as zero or a negative number, whereas the function requires a positive integer to define the number of buckets.
Incorrect Data Types
One or more arguments (e.g., `operand`, `min_value`, `max_value`) are not of a compatible numeric type or cannot be implicitly cast, leading to a data exception.
NULL Argument Values
One or more of the required arguments (`operand`, `min_value`, `max_value`, `num_buckets`) are supplied as NULL, which is not permitted for these parameters.
