Thats what i do for intarray:
-Install all contrib packages you want to use (*before* restoring
your DB)
-Restore Your DB
-Look in log for errors
-Correct them.
Normally all you shoud get is a bunch of notices that somethings
are allready defined.
I had the same problem as you with gist indexes in intarray.
