ERROR: Function 'format_type(oid, int4)' does not exist

I am converting my PostgreSQL data    base to 7.1.2.  I dumped my database
out of the old server, then dumped it into the new one.  Everything takes
okay, but my Indexes are not working.  When I do a "\d" it lists the Name,
Type, and Owner, but when I try and do a \d on a specific table, I get this
error:

customer=# \d pods
ERROR:  Function 'format_type(oid, int4)' does not exist
        Unable to identify a function that satisfies the given argument
types
        You may need to add explicit typecasts

Here are the creation lines:

customer=# CREATE TABLE "pods" ("pod_id" int4,"group_id" int4,"description"
character(30));
CREATE
customer=# CREATE UNIQUE INDEX "pods_pod_id_key" on "pods" using btree
 "pod_id" "int4_ops" );
CREATE

and I can view the index I just created:

customer=# \di pods_pod_id_key
        List of relations
      Name       | Type  | Owner
-----------------+-------+-------
 pods_pod_id_key | index | root
(1 row)

Any ideas?

Thanks!
