+## 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>;
+```
