I've added wkb_recv and wkb_send in the list of obsoleted functions
handled by postgis_restore.pl. Could you try current (CVS) version ?
Would you send a list of other uncought obsoleted functions ?

Be aware (if you're going to patch postgis_restore.pl yourself) that
some failures are due to different output from different versions
of pg_restore.

Note finally that the errors you're getting won't hurt unless the
restore call is interrupted by the error (ie. transactional).
