RemoveTempResolvedColumn

object RemoveTempResolvedColumn extends Rule[LogicalPlan]

The rule ResolveReferences in the main resolution batch creates TempResolvedColumn in UnresolvedHaving/Filter/Sort to hold the temporarily resolved column with agg.child.

If the expression hosting TempResolvedColumn is fully resolved, the rule ResolveAggregationFunctions will - Replace TempResolvedColumn with AttributeReference if it's inside aggregate functions or grouping expressions. - Mark TempResolvedColumn as hasTried if not inside aggregate functions or grouping expressions, hoping other rules can re-resolve it. ResolveReferences will re-resolve TempResolvedColumn if hasTried is true, and keep it unchanged if the resolution fails. We should turn it back to UnresolvedAttribute so that the analyzer can report missing column error later.

If the expression hosting TempResolvedColumn is not resolved, TempResolvedColumn will remain with hasTried as false. We should strip TempResolvedColumn, so that users can see the reason why the expression is not resolved, e.g. type mismatch.
