Representation of a union with its list of operands, and optional order by and limit. A union materializes its results, and its resultExprs are slotrefs into the materialized tuple. During analysis, the operands are normalized (separated into a single sequence of DISTINCT followed by a single sequence of ALL operands) and unnested to the extent possible. This also creates the AggregationInfo for DISTINCT operands.

Creates sortInfo by resolving aliases and ordinals in the orderingExprs. If the query stmt is an inline view/union operand, then order-by with no limit with offset is not allowed, since that requires a sort and merging-exchange, and subsequent query execution would occur on a single machine. Sets evaluateOrderBy_ to false for ignored order-by w/o limit/offset in nested queries.

Create a tuple descriptor for the single tuple that is materialized, sorted and output by the exec node implementing the sort. Done by materializing slot refs in the order-by and result expressions. Those SlotRefs in the ordering and result exprs are substituted with SlotRefs into the new tuple. This simplifies sorting logic for total (no limit) sorts. Done after analyzeAggregation() since ordering and result exprs may refer to the outputs of aggregation. Invoked for UnionStmt as well since TODO: We could do something more sophisticated than simply copying input slotrefs - e.g. compute some order-by expressions.
