[postgis-users] Major Differences between 8.0 and 8.1?

[Sears, Jeremy]

Hi All,
Im wondering if anyone can point out for me the major differences between
PostgreSQL 8.0 and 8.1.

Im running 8.1 on win server 2003. I have PostgreSQL 8.0 running on another
server. For the sake of trouble shooting a database connection issue with
the 8.1 server, I have been requested to put 8.0 on the server that's
running 8.1. Is it possible to simply copy the files from my 8.0
installation into the directory of my 8.1 installation? Would any OS changes
have to be made to allow such a move to function properly?

Best Regards
Jeremy
