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.
