Problems appear if you migrate to 8.3 or higher (due to explicit conversions in data types and tsearch changes). But moving from 8.1 to 8.2 should be really easy and shouldn't suppose a problem.

Subject: Disparity between 8.1.18 and 8.2.14 performance wise
Date: Mon, 22 Mar 2010 17:58:41 -0400
After many days of googling and referring to different web pages about performance, I'm turning to this list for help. We have a third party application that is running on 8.1.11 and the vendor has told us not to upgrade the database to 8.2.
