------------------------------------------------------------------
Back to this issue, method
DataSourceNode#computeOperatorSpecificDefaultEstimates only calls
format#configure, doesn't call format#close. In my opinion, method
computeOperatorSpecificDefaultEstimates should close the format, in another
word, which configure the format should be responsible for closing the format.
[~jark], what do you consider about?
