Default databases

New clusters and existing clusters upgraded to v2.1 or later will include three auto-generated databases, with the following purposes:

  • The empty defaultdb database is used if a client does not specify a database in the connection parameters.

  • An empty database called postgres is provided for compatibility with Postgres client applications that require it.

  • The system database contains CockroachDB metadata and is read-only.

The postgres and defaultdb databases can be deleted if they are not needed.
