## Impact

PostgreSQL can create a temporary file for actions such as sorting, hashing and temporary query results when these operations exceed *work\_mem*. The *log\_temp\_files* flag controls logging names and the file size when it is deleted. Configuring *log\_temp\_files* to zero (*0*) causes all temporary file information to be logged, while positive values log only files whose size are greater than or equal to the specified number of kilobytes. A value of *-1* disables temporary file information logging. We recommend you set the *log\_temp\_files* database flag for Cloud SQL PostgreSQL instances is set to zero (*0*). If temporary files are not logged, it may be difficult to identify potential performance issues caused by either poor application coding, or deliberate resource starvation attempts.

## How to Fix

*Resource:* google\_sql\_database\_instance

* *Arguments:* database\_version = "POSTGRES\_\* " settings::database\_flags: key:"log\_temp\_files", value: by default set to "-1" \[source,go]

***

resource "google\_sql\_database\_instance" "default" { name = "master-instance" database\_version = "POSTGRES\_11" region = "us-central1"

settings {

* database\_flags {
* name = "log\_temp\_files"
* value = "0" } } }

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/logging/appsec-gcp-56.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
