Comment (by pramsey):

 Stripping it down to the minimum amount of SQL, no upgrade required,
 assuming you have done `make install` on both postgis 2.1.8 and svn trunk:
 {{{
 DROP DATABASE IF EXISTS pg21;
 CREATE DATABASE pg21;
 \c pg21
 SELECT postgis_raster_lib_version();
 CREATE EXTENSION postgis VERSION '2.1.8';
 CREATE OR REPLACE FUNCTION bytea(raster)
     RETURNS bytea
     AS '$libdir/rtpostgis-2.3', 'RASTER_to_bytea'
     LANGUAGE 'c' IMMUTABLE STRICT;
 }}}
 Basically get the old library loaded, then bring in the new one, which
 causes the _PG_init() hook to run. Then things fall apart on Ubuntu (but
 not on OSX)
