Hello, I have a redhat E5 installation with PostgreSQL 7.4 installation. I have been tasked with upgrading it to 9.x
I have read that I can install both versions at the same time via YUM and edit the config file on the new installation to use a different port until go live time. Can anyone confirm if this is true? I also read this is the ideal way to go so I can use the newer version of pg_dumpall to transfer the data because the newer version contains bug fixes and other efficiencies. Thanks for your advice. Randy
