 When I try to upgrade this:

 "POSTGIS="2.0.0alpha7SVN r9347" GEOS="3.4.0dev-CAPI-1.8.0"
 PROJ="Rel. 4.8.0, 20 February 2012" GDAL="GDAL 1.9.0, released
 2011/12/29" LIBXML="2.7.8" USE_STATS (core procs from
 "2.0.0alpha7SVN r9322" need upgrade) (raster procs from
 "2.0.0alpha7SVN r9322" need upgrade)"

 with rtpostgis_upgrade_20_minor.sql

 I get:

 Error:  cannot drop function st_union(raster, text)because extension
 postgis requires it
