Lakebase Postgres Autoscaling

FIRST: Use the parent databricks-core skill for CLI basics, authentication, and profile selection.

Lakebase is Databricks' serverless Postgres-compatible database, available on both AWS and Azure (GA). It provides fully managed OLTP storage with autoscaling, branching, and scale-to-zero.

Provisioned Lakebase no longer exists — never create it. The old Provisioned tier (static, non-scalable Postgres; databricks database CLI / w.database SDK) is being migrated to Autoscaling over summer 2026, with no customer action required. Lakebase today is Autoscaling-only (databricks postgres / w.postgres). Do not attempt to create Provisioned instances; if a user asks for one, tell them Provisioned instances don't exist anymore and point them to Autoscaling. Treat the legacy database resource key in app configs as retired — migrate to the postgres resource key. For the legacy DAB synced_database_tables resource, use the databricks postgres create-synced-table CLI flow instead (see the Common Issues row and references/synced-tables.md).

For context when reading older configs or docs, here is how the retired Provisioned tier maps to Autoscaling:
