Because of this, avoid creating objects in template1 unless you want them propagated to every newly created database. This means that any changes you make in template1 are propagated to all subsequently created databases. Whenever you create a new database within the cluster, template1 is essentially cloned. So if you type psql without database name, you will be connected to the default postgres database. If you do not specify any database at connection time, you will be connected to the postgres database. The postgres database is the default database which is created using template1 database. ![]() When PostgreSQL cluster is initialized, template0, template1 and postgres databases are created.
