Summary
During the second run of an incremental materialization, the adapter would try and fetch records from the temporary table it is creating. This made the adapter hang if the table was large enough.
Description
Made the fetch configuration false by default. Also changed the run_query macro to use call_statement, as run_query will always fetch the data that is returned by the sql query. Thanks to @mxmarg for the initial iteration of this fix.
