I have been tasked with investigating an upgrade from 7.3.8 to 8.1.5. I have spent the last 12 years as an Ingres DBA, and am new to PostgreSQL. I know database theory, but not the specifics of this one I am sure that there will be benefits of upgrading, but are there any known problems with upgrading ? Please also let me know if it is a painless transition. Thanks in advance for any useful replies Craig
