This is not a flame about current or previous release of Postgres. I have just gone through the awful experience of upgrading from Postgres 8.2 to 8.3 with a database that had one of the many Postgres extensions included. The problem comes down to the way that Postgres extensions are packaged up, each extension tends to define some extension specific functions, when you do a dump of the database these functions get include. If upgrade from one version of Postgres to another, you take a dump of the database, which then needs to be upgrade if there have been any changes in the extension. The problem being that there doesn’t seem to be a way of dumping the database with out including extension specific information.
There is a possible solution to this problem, move all the extension specific functions to an extension specific schema. That way the contents of the database are kept separate from extensions. For example the postgis function area would change to postgis.area assuming the the schema for postgis extension was call postgis, this would also avoid the problem if two extensions happen to have a function with the same name.
