The PostgreSQL plugin warns on empty tables, as it seems the vacuum / analyse checks are just based on age and does not take table stats into account.
It makes no sense IMHO to warn when table is empty, or better: when pg_stat_all_tables.n_tup_ins, pg_stat_all_tables.n_tup_del and pg_stat_all_tables.n_tup_upd are 0.
autovacuum is configurable in postgresql.conf by many parameters, so I’m wondering what this check is all about for now without checking the configuration and table stats.
