How to extend#
Proposals to extend this list are welcome in the project repository: https://gitlab.com/postgres-ai/custom-images.
tip
If needed, you can specify any custom Docker image with PostgreSQL in the Database Lab Engine configuration. There is one requirement: such an image needs to use the directory /var/lib/postgresql/pgdata as PostgreSQL data directory (PGDATA).
Use this Dockerfile as an example. You can extend or modify it for your needs.
