# Duplicate A Local Database
|
|
|
|
You can quickly create a new database instance that is a duplicate of another
|
|
database. If the existing database is local, you don't need to dump and
|
|
restore. Instead you can use the `createdb` command that comes with Postgres:
|
|
|
|
```bash
|
|
$ createdb -O ownername -T originaldb newdb
|
|
```
|
|
|
|
This creates a new database called `newdb` using `originaldb` as a template
|
|
(`-T`). This will include the entire schema and data of the original database.
|
|
The `-O` flag allows you to specify the owner of the database. Since this is
|
|
local, you probably want your primary unix user as the owner.
