So, here's what we need for 8.3 --> 8.4 for contrib modules:
1) make a list of contrib modules which do not convert cleanly (testers?)
2) document these.
3) give pg_migrator some hackish way to install 8.4 contrib modules from
source before copying over the database.
4) set pg_migrator to ignore duplicate object warnings if it does the above.
Note that we expect NOT to have this issue for 8.4-->8.5, since we'll
have a full module infrastructure by then. Really!
