Frank McQuillan commented on MADLIB-858:
----------------------------------------
Docs say
"The name of the schema where the final results will be stored. It is expected
to be created before calling the function, or using NULL suggests the current
schema will be used."
but some improvement in future to make schema an optional param might be a good
idea.
