The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/15/database-roles.html Description:
In chapter 22.1 the following text seems to imply the role will have "the same name as the user that initialised" it and also the "role will be named postgres". Which cannot both be true, or perhaps the text is trying to say something else, but in doing so is not clear. "This role is always a “superuser”, and by default (unless altered when running initdb) it will have the same name as the operating system user that initialized the database cluster. Customarily, this role will be named postgres. "
