[SOLVED] Magnolia fresh installation

Magnolia fresh installation

I am trying to install Magnolia 6.2.17 on Postgres. I have changed appropriately the "jackrabbit-bundle-postgres-search.xml" to point to Postgres server (tables are create in the DB)

At "core" module installation, after bootstrapping [mgnl-bootstrap/core/config.server.security.xml] and so after ObservedComponentFactory: Re-loaded info.magnolia.cms.security.SecuritySupport from node /server/security,

I have this error (sometimes with '/admin' other with '/system')

ERROR info.magnolia.cms.security.SystemUserManager     : Failed to get system user [superuser], will try to create new system user with default password 
ERROR info.magnolia.cms.security.MgnlUserManager       : Could not retrieve user with name: superuser
javax.jcr.PathNotFoundException: /admin

Installing Magnolia on embedded H2 is all ok.

Someone can help me ?

Thanks
