It sounds like line_function is careless about its search path
assumptions. auto-analyze will run index expressions with the
search_path set to empty (i.e., only pg_catalog is accessible)
and hstore isn't normally installed in pg_catalog.
The easy fix would be to attach "SET search_path = public"
to that function, but I believe that destroys the ability to
inline it, which might be a performance problem for you.
Alternatively you could schema-qualify the operator name,
that is "foo OPERATOR(public.->) bar".
