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.
