Comment (by pramsey):

 Fix 3:

 * From my colleague @javitonino, we can just add `SET SEARCH_PATH =
 @extschema@, pg_catalog` in the function definition itself.  As the manual
 for https://www.postgresql.org/docs/9.5/static/sql-createfunction.html
 create function notes, we can add `SET` clauses there.

 Unless someone has a screaming reason why this is not right, I think
 `st_transform` and `postgis_transform_geometry` can be upgraded with this
 small fix, and that should probably be backported as well, so other fresh
 installs get the right schema qualifications right up fron..
