    • OR_SETUP_RUN_ON_RESTART

      public static final String OR_SETUP_RUN_ON_RESTART
      We must use a different schema than Keycloak to store our tables, or FlywayDB will wipe Keycloak tables. And since Keycloak doesn't call CREATE SCHEMA IF NOT EXISTS on startup (Liquibase is not as good as FlywayDB? They both seem to suck... can't exclude database artifacts from wipe/migrate in FlywayDB...) you must have it in the 'public' schema. Hence we need a different schema here.
