Extension UPDATE: ERROR: cannot change name of input parameter "band"

[strk]

From:

 POSTGIS="2.1.0SVN r10603" 
 (core procs from "2.1.0SVN r10237" need upgrade) TOPOLOGY (topology procs from "2.1.0SVN r10237" need upgrade) RASTER (raster procs from "2.1.0SVN r10237" need upgrade)

You can not soft-upgrade to 2.1.0SVNnext:

pg21=# ALTER EXTENSION postgis UPDATE TO "2.1.0SVNnext";
ERROR:  cannot change name of input parameter "band"

Sounds like a missing DROP of the function whose input parameter name was changed.

Please think more before changing a parameter name. I know it is nice to have semantically correct param names, but it's a big obstacle to CREATE OR REPLACE FUNCTION.
