upgrading from V8.3.4 to V9.2.4

[Paul Tilles <paul.tilles@xxxxxxxx>]

We are going to be upgrading our postgres version from 8.3.4 to 9.2.4 in 
the near future.

Can anyone give me a short list of "gotchas" concerning problems we 
might step into?

We have a number of functions written in PL/pgSQL.  Will they work in 
9.2.4 without modification?

Thanks in advance to the Community for your help.
