None, it's just an extension.

Which is part of what is so awesome about PostgreSQL, everyone can build extensions that look and feel native and can do almost anything.

You should review the PostgreSQL trademark policy: https://www.postgresql.org/about/policies/trademarks/

You might want to use a different elephant logo... the branding implies that it is an official part of the project.

E.g. Postico uses an elephant but not the _same_ elephant - https://eggerapps.at/postico/

I think the logo is clever, and if there’s no rights issue it’s great. The fact that it’s a different website, domain, theme etc doesn’t make it ambiguous IMO

This logo and name, to me at least, implied some sort of official affiliation with the PostgreSQL project. Which I think should at least be clarified on the site/readme.

I found this to be very confusing and took some sorting out that this is not an official project of postgresql. I personally think a name change and logo redo is in order here.
