Description:
The same SQL query can be excuted in multiple ways and still produce different results. The PostgreSQL planner/optimizer is responsible to create an optimal execution plan for each query. The 'log_planner_stats' flag controls the inclusion of PostgreSQL planner performance statistics in the PostgreSQL logs for each query.
Rationale:
The 'log_planner_stats' flag enables a crude profiling method for logging PostgreSQL planner performance statistics which even though can be useful for troubleshooting, it may increase the amount of logs significantly and have performance overhead. This recommendation is applicable to PostgreSQL database instances.
Using Console:
Using Command Line:
gcloud sql instances list
gcloud sql instances patch INSTANCE_NAME --database-flags log_planner_stats=off
Note: This command will overwrite all database flags previously set. To keep those and add new ones, include the values for all flags you want set on the instance; any flag not specifically included is set to its default value. For flags that do not take a value, specify the flag name followed by an equals sign ("=").
