I am trying to install TYPO3 11.5.17 with PostgreSQL 14.5. I tried to follow this guide, but in step 2, only MySQL options are shown for me. This is a discrepancy to the screenshot. I tried to troubleshoot this, but pages like this are written for outdated versions. I could not find newer pages that are saying anything else than "it works with PostgreSQL". However, I am obviously missing something that needs to be done. As all pages that help troubleshooting this issue are written for versions with different file structure, I am out of ideas now. How can I get PostgreSQL to show up in the installer?

Followup question: I was not too happy about the idea to run two separate DBMSs on one server. PostgreSQL is already needed for other services. However, if anybody can come up with a good point about why TYPO3 runs much much better with MySQL, I will consider this new information.

Maybe you missed the needed PHP Database Extensions to handle postgreSQL?

see the System requirements regarding the needed extensions.
