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?
