Would it make any sense to modify the incremental approach to do a first pass of any tables with target overrides, using the default GUC setting, and then proceed through the passes you describe for all tables *except* those? I'm thinking that any overrides were probably set because the columns are particularly important in terms of accurate statistics, and that running with different GUC settings will just be a waste of time for those tables -- if they have a high setting for any column, they will sample more blocks for every run, right? -Kevin
