At a quick glance, I don't see it called in the select-list  in any
of the regression tests. When trying it, it appears to crash (segfault):

postgres=# begin;
BEGIN

postgres=# declare c cursor for select oid::int as i, relname::text as r from
pg_class;
DECLARE CURSOR

postgres=# select unnest('c'::refcursor);
server closed the connection unexpectedly
	This probably means the server terminated abnormally
	before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.

The build is configured with:
./configure --enable-debug --with-icu --with-perl --enable-depend
