The new version will update your postgresql packages. It shouldn't wipe your data files, since /etc/init.d/postgresql script checks if there are data in the specified directory. Then you must erase those postgresql (rpm -qa|grep postgres will list packages installed), and install yours. But, if new subversion is the same (example 7._4_.8 and 7._4_.9 but it's and unchecked and probably not real example), the script could run and the engine will run (it won't delete your files). I would perform a backup anyway. -----Mensaje original----- De: pgsql-admin-owner@xxxxxxxxxxxxxx [mailto:pgsql-admin-owner@xxxxxxxxxxxxxx]En nombre de FM Enviado el: miércoles, 19 de octubre de 2005 12:47 Para: Mailing List Postgres-Admin Asunto: install new version of Redhat without deleting /var/lib/pgsql ? Is it enough ? Hello erverybody, I need to install a new version of Redhat on my server. On the distro, pgsql data are in : /var/lib/pgsql (which is mounted on its own partition). Can I "just" install the new version of Redhat, reinstall the same version of Postgresql (7.4.8) ? I'll do a pgdump all just in case Thanks ! ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
