  Further information
 
 1. After every call to an Executor-related function or procedure, you should check the value of
 getstatus to see if your request succeeded. If it's unclear why an error is being returned, more troubleshooting output can be generated by setting the parameter
 executor_verbose to true, or inspecting the return value of
 getlasterror.
 
 2. This function returns human-readable English description of the error that may be useful for troubleshooting purposes, but you should not assume that it is in any particular format. To distinguish between different types of error, use
 getstatus instead.
