DLE v3.0.0-rc.1 includes several major changes and many improvements. Most notable changes are:

  • persistent clones: clones now survive DLE (or VM) restart,
  • GUI included to the core, it allows working with a single DLE instance,
  • PostgreSQL 14 support.

Please note that upgrading from an older version requires some actions from the DLE administrator (see "Migration notes" below).

The list below has "WIP" status. The final list for the 3.0 major version release may include some changes.

The development team asks everyone to participate in testing and report any bugs or improvement ideas in the DLE repository: https://gitlab.com/postgres-ai/database-lab.

Migration notes

The Database Lab configuration contains a new section localUI to run UI application that allows observing the current state of the instance and performing basic clone operations:

localUI:
  enabled: true
  dockerImage: "postgresai/basic-ui:latest"
  host: ""
  port: 2346

Note, this application is delivered as a separate Docker container (Local UI) and running by the Database Lab Engine.

Since v3.0.0-rc.1, DLE collects non-personally identifiable telemetry data.
The Engine uses anonymous usage data to assist users and improve product quality.

it is possible to manage the configuration in the section global:

global:
  telemetry:
    enabled: true
    url: "https://postgres.ai/api/general"
    ...

Please leave it enabled if possible – this will contribute to Database Lab development.
See more details on the Telemetry page in the docs

Now it is available to select a specific pool to work with, use a new option selectedPool in the poolManager section

poolManager:
  selectedPool: "dblab_pool"
  ...

Since version v3.0.0-rc.1, Database Lab Engine can be running with an empty verification token, which is not recommended by default.
In such a case DLE warns about empty token in instance logs and API will not require any credentials. Be sure that this option is configured correctly

In order to make the management of service containers easier, special labels have been added to them:

- `dblab_instance_id`: <dle_instance_id>
- `dblab_engine_name`: <dle_container_name>

For example, there is a snippet of the docker inspection response of a sync instance:

"Labels": {
    "dblab_control": "dblab_sync",
    "dblab_instance_id": "c64mvrvku3086hlp2e6g",
    "dblab_engine_name": "dblab_server",
    "maintainer": "postgres.ai"
}
