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/

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.
