## Postgresql

### Creating a user and the database

To create a new user within postgresql, enter the shell via `helperbot --psql`.

First we'll create the user. Use the following:
```sql
CREATE USER <user> WITH ENCRYPTED PASSWORD '<password>';
```

Now within the shell, you can just. Type in `\q` to quit.
```sql
CREATE DATABASE <db name>;
```

Now you need to give the user proper permissions to access the database, otherwise it will fail to work with whatever application we want to hook it up with.
```sql
GRANT ALL PRIVILEGES ON DATABASE <db name> TO <user>;
\c <db name> -- switch to the database
GRANT ALL ON SCHEMA public TO <user>;
```

If you ever need to delete a user and their database:
```sql
DROP DATABASE <db name>;
DROP USER <user>;
```
