Add the database cluster's config files postgresql.conf, pg_hba.conf, pg_ident.conf or whatever to the tar file. Then, on the new host, do an initdb and after that, copy the old config files into the new PGDATA. Then start the new (empty and free of databases) database cluster. So: tar cvf /tmp/postgresql11.tar /usr/local/sisis-pap/pgsql /data/postgresql11/*.conf Cheers, Paul
