Two categories of parse errors prevented the PrometheusRule from being accepted when monitoring.enabled=true: 1. CNPGClusterLogicalReplicationErrors and CNPGClusterLogicalReplicationErrorsCritical: `increase()` was wrapping `max by()(A + B)[5m]`, applying a range selector to an aggregated instant vector, which is illegal in PromQL. Fix: apply `increase([5m])` to each individual metric selector before aggregating. 2. CNPGClusterLogicalReplicationStopped and CNPGClusterLogicalReplicationStoppedCritical: `cnpg_pg_stat_subscription_pid` (a numeric gauge) was compared with `""` (a string), which is not a valid PromQL binary expression. Fix: compare with `0` instead. Signed-off-by: Allex1 <Allex21ro@yahoo.com>
