So the question is, did you have your template1 customized in the 8.4
installation and are you looking to transfer those added items to the 9.1
installation? Some information on the template system can be found here:
http://www.postgresql.org/docs/9.1/interactive/manage-ag-templatedbs.html
As others have said you can recreate a bare template1 from template0. If you
had not customized template1 that should do. If you had customized it:
On the chance that the 8.4 cluster is still up and running you could just do a
pg_dump of template1 on that cluster and load it into the new cluster. If the
8.4 cluster is not running you can go to your pg_dumpall file and get the
template1 objects from there. Search for the \connect template1 string and look
for the SQL commands until the next \connect string.
