What are Template Databases in PostgreSQL | A deep dive
This video provides a summary of template databases in PostgreSQL.
Key concepts covered in the video:
Viewing databases: You can list all available databases using the \l command in the psql terminal [00:21].
Template databases: PostgreSQL comes with two default template databases: template0 and template1 [00:27]. These are used as blueprints to create new databases.
template1 vs. template0: template1 is the default template for new databases [01:21], while template0 is a pristine copy that cannot be modified or connected to directly [01:31].
Creating a new database: A new database can be created using the CREATE DATABASE command, which by default copies from template1 [04:00].
Restricting connections: You can prevent connections to a database by updating the datallowconn variable to false [05:08].
