Hello All,
Thanks for the excellent help and suggestions.
I followed this tutorial (https://bitbach.wordpress.com/2014/08/2 ... ntu-14-04/) on upgrading postgres 9.1 to 9.3 and other than switching the ports for 9.3 to the default 5432 the upgrade process went perfectly.
I then was able to upgrade the Omero database without any problems and now am running 5.1.2.
I removed postgres 9.1 and the associated client as well.
Again, your help has been fantastic.
Best regards,
Wade
