So the question remains, why autovacuum is not checking this column first and then skip other calculations in the case, the table is not activated at all. Thinking more forward: would it make sense to have some kind of helper in the database which gives (if enabled) notices back, if you are doing something crazy? As example insert a value into a serial column (would not be wrong and can be perfectly valid but for a beginner this could just be a problem), maybe some helps from the planner about index usage or missing index or in case of pg_autovacuum give some hints about values which seem to create problems.
