Clearly Postgres is not a good database and you will wisely use any other. I can see real advantages to this. It saves you so much effort and time. In fact, it allows you to make no effort at all.
I have never heard anyone mispronounce postgres. It's even more straightforward than Gitea, which native-roman-language-speakers might pronounce "git-tay-ah"
You're missing the fact that the name is not even Postgres, it's PostgreSQL, /ˌpoʊstɡrɛskjuˈɛl/ POHST-gres-kew-EL. It's so awkward people actively avoid even typing it!
