I just tested this under 6.1 of pg_dumpall, and got:
CREATE UNIQUE INDEX specialization_index on specialization using btree
(strcatc2c16 (code, statebarnum) char_ops );
So it looks like it was broken in 6.0, but fixed in 6.1, which doesn't
help your migration from 6.0, but shows it will work when you dump 6.1.

There is a Money type in 6.1, but it does not have a user-defined
length, yet.
