No, not really. You could maybe un-drop the columns with some manual
surgery on pg_attribute, but it doesn't seem like that's going to lead
to a nice solution.
If you were really desperate you could try back-porting the patch:
http://archives.postgresql.org/pgsql-committers/2009-08/msg00068.php
but I wouldn't want to vouch for its safety, considering it hasn't
been through a beta test cycle yet.
