A Correct answer
Explanation

The system limits keyword functions to a maximum of 63 characters. This is a common technical constraint in many systems that ensures manageable function names and prevents excessively long identifiers.

AI explanation

In PostgreSQL (and several other systems), identifiers such as function names are limited to a maximum of 63 characters — longer names are silently truncated or rejected. This 63-character limit comes from the internal NAME data type, which reserves 64 bytes total (63 usable characters plus a terminator).
