ParameterValue
ParameterValue =
null|boolean|bigint|number|string|Uint8Array|Timestamp|Duration|ParameterValue[]
One predicate parameter in JavaScript form.
An integer arrives as bigint so that a 64-bit value keeps its exact
magnitude. A timestamp and a duration arrive as their protobuf well-known
types, because a target column can store either one in several ways and this
package does not choose one for the caller.
