This is needed because the PagesPruningStatistics is not in terms of the StatisticsConverter code yet. I will try and do that in a separate PR and avoid the need for this

this is necessary to convert from ArrowError to DataFusionError

can we use map_err? or into?

Thank you for the suggestion.
I played around with a few alternatives and I concluded they were not easier to understand, so I plan to leave it as is. If you feel strongly I will make a follow on PR to change.
I couldn't figure out a way to use into()
Option 1: using map_err
fn min_values(&self, column: &Column) -> Option<ArrayRef> {
self.statistics_converter(column)
.and_then(|c| {
c.row_group_mins(self.metadata_iter())
.map_err(DataFusionError::from)
})
.ok()
}Option 2: discard error earlier with ok()
Now there are two nested ok()s
fn min_values(&self, column: &Column) -> Option<ArrayRef> {
self.statistics_converter(column)
.ok()
.and_then(|c| c.row_group_mins(self.metadata_iter()).ok())
