1.) During our prior upgrade process we used pg_upgrade to move from pg 8.4.3 to 9.1.6 using the hard links install option, we also have our data spread across disk storage mediums; fiber, nas. Are there any known issues, bugs with using pg_upgrade to move from 9.1.6 to pg 9.3?
2.) We also have to stand up a fresh install of pg 9.3 with postgis 2.1 and restore the data from a 9.1.6 dump. Are there any known issues, bugs with using pg_dump or pg_dumpall and then pg_restore to get this done?
thanks
