I have a Postgressql-9.2 database with postgis-2.0 in production service. Due, I think, to a bad postgis upgrade, there are both old and new functions present. I am planning to install Postgresql-9.3 and Postgis-2.01 and then copy the data over with pg_upgrade. My question is: Will this also copy over the old functions? If so, how to I copy just the data?
