HOW

Client is exported as a constructor function and Client.prototype.query is a function
Client.prototype.query throws TypeError when query configuration is null or undefined
Client.prototype.query throws TypeError when callback argument is not a function
Client.prototype.query accepts and returns custom submittable query objects
Client.prototype.query executes simple text queries and resolves with query result rows, rowCount, and field metadata
Client.prototype.query executes parameterized queries with positional parameters
Client.prototype.query executes queries specified with query config objects
Client.prototype.query supports callback-style invocation with error and result arguments
Client.prototype.query rejects with DatabaseError when the server returns an error response
