I see your point. How is this?
Allow auto_explain to log query parameters used by parameterized
statements (Dagfinn Ilmari Mannsåker)
This affects queries using server-side PRAPARE/EXECUTE
and client-side parse/bind. Logging is controlled by
auto_explain.log_parameter_max_length; by default query
parameters will be logged with no length restriction.
