Just invoking code doesn't seem to be enough.  I tried just using the
Hstore data type, and then loading hstore_plperl, but that still didn't
work.  It seems like only CREATE EXTENSION loads *all* the symbols.

The latter would be ideal, but I don't know that we currently have any
mechanism for it.
