I think possibly you don't understand how to use those scripts.
The right thing to do is (1) dump your 8.3 database and load into an
empty 9.5 database, then (2) in that new database, execute
CREATE EXTENSION tsearch2 FROM unpackaged;
to convert 8.3's loose clutter of tsearch2 objects into a proper
extension. Trying to load the extension first is just going to
make a mess. Trying to execute both of those scripts is also
going to be a mess --- you only want to use one or the other,
depending on what you're doing.
