<p dir="auto">Hi, this is the reason your contribution was rejected <ul> <li>Tutorials must be technical instructions that teach non-trivial aspects of an open-source project. Everything in this tutorial is very trivial and of little to no value - the use of simple commands that you show in all your videos, like <code>ceil(), are already extremely straight-forward and well documented. It is also not unique to PostgreSQL and ubiquitous. Moreover the linked repository for all your PostgreSQL tutorials is a development repository for the PostgreSQL cookbook, I'm pretty sure the correct repository is <a href="https://github.com/postgres/postgres" target="_blank" rel="nofollow noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">this one instead. <p dir="auto">I recommend you stop making SQL tutorials where you pick 4-6 simple commands and execute them, as they will not be accepted since they are too trivial. Try to think of something that will be considered a valuable contribution to Utopian.io. <p dir="auto">You can contact us on <a href="https://discord.gg/uTyJkNm" target="_blank" rel="nofollow noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">Discord.<br /> <strong><a href="https://utopian.io/moderators" target="_blank" rel="nofollow noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">[utopian-moderator]
