# iai databases update

Update a database in a project

## Synopsis

Partial update of a database. Only the flags you pass are applied; everything else keeps its current value.

Storage can only be increased. Use --clear-backup to disable backups entirely. Changing the PostgreSQL major version triggers an automatic upgrade with cluster downtime.

Use --clear-stack-id to remove the database from its stack.

```
iai databases update <database_name> [flags]
```

## Examples

```
  iai databases update my-db --instances 3
  iai databases update my-db --cpu 2 --memory 4G
  iai databases update my-db --storage-size 50G
  iai databases update my-db --backup-schedule "0 0 3 * * *" --backup-retention 60d
  iai databases update my-db --clear-backup
  iai databases update my-db --stack-id my-stack
  iai databases update my-db --clear-stack-id
```

      --extensions stringArray    PostgreSQL extension to install (can be repeated); replaces the default list, so include "vector" explicitly if needed; defaults to [vector] if omitted

  -o, --organization string       Organization name
      --postgres-version string   PostgreSQL major or major.minor version (e.g. 18, 17.6); supported range 15–18; defaults to latest if omitted

      --stack-id string           Stack ID to assign the database to
      --storage-size string       Storage size with G unit (e.g. 20G, 100G); must be between 10G and 200G; cannot be decreased

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://docs.interactive.ai/cli/iai_databases_update.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.
