How to choose postrgres database when installing gerrit 3.1?

Question

PostgreSQL

I run the command java -jar /var/gerrit/bin/gerrit.war init --install-all-plugins -d /var/gerrit/ , mysql, psql, etc.), and if version 3, then there is no choice of database type at all. I tried to manually cook the gerrit.config file and manually set the settings for the database, but it seems to ignore it and does not work.
Tell me how to set up gerrit version 3 to work with the postgres database?
