Comment (by strk):

 Ok one reason to strip the ALTER is that some of the ALTERs in there are
 for adding constraints, and fail if the constraint already exists. I guess
 the topology script could be changed to account for that, or otherwise it
 would be impossible for an upgrade to add or drop a constraint...

 DROP .. IF EXISTS .. is only available starting with PostgreSQL 9.2 though
