Information

Ensure that the log_checkpoints database flag for the Cloud SQL PostgreSQL instance is set to on.

Rationale:

Enabling log_checkpoints causes checkpoints and restart points to be logged in the server log. Some statistics are included in the log messages, including the number of buffers written and the time spent writing them. This parameter can only be set in the postgresql.conf file or on the server command line. This recommendation is applicable to PostgreSQL database instances.

Solution

From Console:

Go to the Cloud SQL Instances page in the Google Cloud Console by visiting https://console.cloud.google.com/sql/instances.

Select the PostgreSQL instance where the database flag needs to be enabled.

Click Edit.

Scroll down to the Flags section.

To set a flag that has not been set on the instance before, click Add item, choose the flag log_checkpoints from the drop-down menu, and set its value.

Click Save.

Confirm the changes under Flags on the Overview page.

From Command Line:

List all Cloud SQL database instances using the following command:

gcloud sql instances list

Configure the log_checkpoints database flag for every Cloud SQL PosgreSQL database instance using the below command:

gcloud sql instances patch INSTANCE_NAME --database-flags log_checkpoints=on

Note:

This command will overwrite all previously set database flags. To keep those and add new ones, include the values for all flags to be 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 ('=').

Default Value:

By default log_checkpoints is off.
