Let table AM insertion methods control index insertion
Previously, the executor did index insert unconditionally after calling table AM interface methods tuple_insert() and multi_insert(). This commit introduces the new parameter insert_indexes for these two methods. Setting '*insert_indexes' to true saves the current logic. Setting it to false indicates that table AM cares about index inserts itself and doesn't want the caller to do that. Discussion: https://postgr.es/m/CAPpHfdurb9ycV8udYqM%3Do0sPS66PJ4RCBM1g-bBpvzUfogY0EA%40mail.gmail.com Reviewed-by: Pavel Borisov, Matthias van de Meent, Mark Dilger
