extension (ltree, pg_trgm) also have the same problem.
drop table if exists t2 cascade;
CREATE EXTENSION ltree;
CREATE TABLE t2 (t ltree);
create index tstidx on t2 using gist (t gist_ltree_ops(siglen=4));
drop extension ltree cascade;
drop table if exists t3 cascade;
CREATE EXTENSION pg_trgm;
CREATE TABLE t3(t text COLLATE "C");
create index trgm_idx on t3 using gist (t gist_trgm_ops(siglen=1));
drop extension pg_trgm cascade;

extension hstore work as expected, no error.
drop table if exists t1 cascade;
create extension hstore;
CREATE TABLE t1 (h hstore);
create index hidx on t1 using gist(h gist_hstore_ops(siglen=1));
drop extension hstore cascade;
on the master branch. i didn't test on other branches.
