Did you run the postgis_upgrade_20_minor.sql and the rtpostgis_upgrade_20_minor.sql \
scripts?

That should not happen.
If, still, after upgrade, "function st_slope(raster, integer, text) does not exist", \
you will have to have a look and clean a bit the list of function available in your \
public schema or create a new database and reexecute the .sql files (postgis.sql, \
spatial_ref_sys.sql and rtpostgis.sql).
BTW the FROM part of your query is useless...
