That's quite a big step up. You skipped 8.2, 8.3 and 8.4 - all major releases. My advise: Test very thoroughly for more
differencesin behaviour. 

One thing to start looking at right away is whether your config parameters still make sense, in case you're re-using
yourold config. Some changed names I think, and there are some new ones you might want to change.

That seems an odd choice for a datatype. What are you trying to accomplish by making it varchar?

And no, of course you can't sum varchars, what kind of output would you expect from that? That an older version of
Postgresdidn't throw an error was probably a bug.
