## Impact

This rule is checking to verify if the 'log\_parser\_stats' flag in the PostgreSQL database is set to 'off'. This flag, when turned on, logs statistical information about query parsing and rewriting. While this might be useful for debugging, it can generate a vast amount of log data significantly consuming disk space, and may potentially lead to performance degradation. Therefore, for optimal performance and saving resources, it is generally recommended to set the 'log\_parser\_stats' flag to 'off' in a production environment.

## How to Fix

*Resource:* google\_sql\_database\_instance

* *Arguments:* settings.database\_flags

To fix the issue, you should ensure that the 'log\_parser\_stats' flag for your PostgreSQL database is set to 'off'. Here is an example of how to do it in your Terraform file:

## The above code is secure because the 'log\_parser\_stats' flag is explicitly set to 'off'. The 'log\_parser\_stats' flag in PostgreSQL enables detailed statistics for the parser stage of query execution, including the number of created and used tokens and the number of created and used parse nodes. Logging these statistics can have a significant performance impact. So, having this flag off helps in reducing the overhead of unnecessary logging, decreasing the chance of slowed performance of your PostgreSQL database. \[source,go]

resource "google\_sql\_database\_instance" "default" { name = "database" region = "us-central1"

database\_version = "POSTGRES\_11"

## settings { database\_flags { name = "log\_parser\_stats" value = "off" } } }

## 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-15.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.
