## Impact

This rule is checking to ensure that the 'log\_planner\_stats' flag for PostgreSQL databases is set to 'off'. The 'log\_planner\_stats' flag is used to enable or disable logging of planner statistics in PostgreSQL. While logging these statistics might be useful for debugging or optimizing purposes, they could potentially contain sensitive information. Furthermore, having this flag set to 'on' could impact the performance of your database due to the overhead of logging. Therefore, it is generally recommended to have this flag set 'off' in a production environment to maintain security and optimal performance.

## How to Fix

*Terraform*

* *Resource:* google\_sql\_database\_instance
* *Arguments:* settings.database\_flags

To fix this issue, you need to add the 'log\_planner\_stats' setting within settings block in the database instance and set it to 'off'. This statement is an example of how you can define a database\_instance:

```hcl
resource "google_sql_database_instance" "default" {
 name = "test"
 region = "us-central1"

 # ...

 database_version = "POSTGRES_9_6"

 settings {
 database_flags {
 name = "log_planner_stats"
 value = "off"
 }

 # ...
 }
}
```

This code is secure because setting the 'log\_planner\_stats' to 'off' ensures that the planner's statistical data is not logged. This helps maintain the security of our database as it may prevent the accidental logging and exposure of sensitive data.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/logging/appsec2-gcp-16.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
