# 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.

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

```
