My answer is, it entirely depends if your application is considered a &amp;quot;derivative work&amp;quot; of Postgres. This hinges on a couple of things:&lt;p&gt;- does your application directly include AGPL postgres code in any form (headers, binary, etc etc) to its own source or its own runtime process?&lt;p&gt;- keep in mind, in answering the above, that your application probably &lt;i&gt;does&lt;/i&gt; have to include a postgresql driver of some kind. Is the driver licensed AGPL too? If yes, your answer to the above is probably &lt;i&gt;yes&lt;/i&gt;. This was the problem for years with MySQL, because they licensed their driver code GPL along with the actual database code.&lt;p&gt;- a final consideration that only comes into play if there is genuine ambiguity on the other points: is your application able to perform its functions if Postgresql is missing or swapped out for another database? To the extent it depends on Postgresql functionality, this will sway a jury towards considering it is in fact a derivative work of Postresql. If you on the other hand support 6 different databases and Postgresql is just one of them - it will be much less likely your application is considered a derivative work of it. As I said, this only comes into play if the other factors can&amp;#x27;t be decided decisively.</text><parent_chain><item><author>watermelon0</author><text>I have a question regarding AGPL, that I couldn&amp;#x27;t answer by Googling or reading the license.&lt;p&gt;Let&amp;#x27;s say that Postgres server is licensed under AGPL, and I modify it to my needs.
