I just tried to add something to the pg_autovacuum table for the first time today (with 8.1). I wanted to make the simplest possible entry: Disable auto-vacuuming for a table. However, the data model requires that I also enter values for: vac_base_thresh vac_scale_factor anl_base_thres anl_scale_factor vac_cost_delay vac_cost_limit None of those values matter when vacuuming is disabled for the table! I suggest all these fields be nullable, and default to global values if they are NULL. These are "guts" and I should have to learn about them or fake them if I just want to disable vacuuming for a table. Likewise, if I just want to set one of the values, I shouldn't have to set /all/ of them if the defaults are otherwise reasonable. For the moment, I suppose I'll go and fake all these values so I can disable a table from Vacuuming. Mark
