Tom Lane d89902f2ee Use @extschema:name@ notation in contrib transform modules.
Harden hstore_plperl, hstore_plpython, and ltree_plpython
against search-path-based attacks by using @extschema:name@
notation to refer to the underlying hstore or ltree data type.

This allows removal of the previous documentation warning
suggesting that they must be installed in the same schema as
the underlying data type.  In passing, also improve a para in
extend.sgml to suggest using @extschema:name@ for such purposes.
