Did you run the postgis_upgrade_20_minor.sql and the rtpostgis_upgrade_20_minor.sql scripts? http://postgis.refractions.net/documentation/manual-svn/postgis_installation.html#soft_upgrade > Thought it could be if I am incorrectly casting the first 8BUI instance so > removed > the first '::text' and error now returns: > "rt_raster_from_wkb: wkb size (2) < min size (61)" 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...
