     !!! warning "Query plan metrics known issue"
         Before configuring `pg_stat_monitor`, make sure that `pg_stat_monitor.pgsm_enable_query_plan` stays disabled. This is because query plans causes `pg_stat_monitor` to create multiple records for each query, leading to incorrect timing calculations.
