The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/13/tutorial-createdb.html Description:
In the getting started documentation, it will have been better to start with how to 'login to postgres' and cover the idea of 'roles'. Or if previously done, refer reader to the relevant section. The explanation on how to use createdb command can follow. This can avoid considerable problems for a user following the tutorial.
