Oh right, adding --no-locale to the regress opts I see that create_index is
failing, and that's not the one I was expecting.

We could change create_index test to create c2 with a C collation, in order to
test that we don't track dependency on unversioned locales, and add an extra
test in collate.linux.utf8 to check that we do track a dependency on the
default collation as this test isn't run in the --no-locale case.  The only
case not tested would be default unversioned collation, but I'm not sure where
to properly test that.  Maybe a short leading test in collate.linux.utf8 that
would be run on linux in that case (when getdatabaseencoding() != 'UTF8')?  It
would require an extra alternate file but it wouldn't cause too much
maintenance problem as there should be only one test.
