Can't upgrade 2.2.0dev to 2.2.0devnext

[strk]

strk=# alter extension postgis update to '2.2.0devnext';
ERROR:  cannot drop function _raster_constraint_nodata_values(raster) because other objects depend on it
DETAIL:  constraint enforce_nodata_values_r on table areas depends on function _raster_constraint_nodata_values(raster)
HINT:  Use DROP ... CASCADE to drop the dependent objects too.

rtpostgis_upgrade_cleanup.sql.in contains:

-- function signature change                                                    
DROP FUNCTION IF EXISTS _raster_constraint_nodata_values(rast raster);

Breaking line added in r13467 supposedly for #3006

[strk]

speaking of which.. we should make our upgrade tests smarter (right now we upgrade with no data tables, we should instead create some data tables first, then upgrade and then remove those tables)

[strk]

This patch for run_test.pl makes it reproduce the issue on "make check" (or whenever it is called with switches —upgrade and —raster):

I'll have to use a fancier DO loop… no simple drops here.

strk, I think you should commit that patch. It's worth it.

[strk]

I'll push the patch as soon as the bug is fixed, don't want to block the work of others closing up the release.

[strk]

I've filed #3120 for the run_test.pl enhancement

Fixed in -trunk at r13510
