Description:        Dump and restore from Slonified 8.1.11 causes a segfault
Details:

Either a pg_dumpall or pg_dump of a Slonified database on PostgreSQL 8.1.11
causes a segfault if I try to restore it on PostgreSQL 8.3.1. Got around it
by restoring onto another 8.1.11 and then did a cascaded drop <slony>
schema. The original Pg one was in production. The resulting dump was then
able to restore on an 8.3.1. Now we have 8.3.1 in production.

If you need more data, let me know since I can reproduce this at will.
