It's possible to build INSERT SELECT queries which include implicit casts, currently we attempt to support these by adding explicit casts to the SELECT query, but this sometimes crashes because we don't update all nodes with the new types. (SortClauses, for instance) This commit removes those explicit casts and passes an unmodified SELECT query to the COPY executor (how we implement INSERT SELECT under the scenes). In lieu of those cases, COPY has been given some extra logic to inspect queries, notice that the types don't line up with the table it's supposed to be inserting into, and "manually" casting every tuple before sending them to workers. |
