Thanks for the push, I found it: It is part of slony which isn't
on the new databases:

mail=> select oid,* from pg_catalog.pg_type where typname='xid';
oid | typname | typnamespace | typowner | typlen | typbyval | typtype |
28 | xid | 11 | 1 | 4 | t | b |

mail=> select * from pg_catalog.pg_cast where castsource=28;
castsource | casttarget | castfunc | castcontext
------------+------------+----------+-------------
28 | 21800 | 0 | i

mail=> select oid,* from pg_catalog.pg_type where oid=21800;
oid | typname | typnamespace | typowner | typlen | typbyval | typtype | typisdefined | typdelim | typrelid | typelem | typinput | typoutput | typreceive | typsend | typanalyze | typalign | typstorage | typnotnull | typbasetype | typtypmod | typndims | typdefaultbin | typdefault
-------+---------+--------------+----------+--------+----------+---------+--------------+----------+----------+---------+------------------------+-------------------------+------------+---------+------------+----------+------------+------------+-------------+-----------+----------+---------------+------------
21800 | xxid | 21799 | 1 | 4 | t | b | t | , | 0 | 0 | _upsreplication.xxidin | _upsreplication.xxidout | - | - | - | i | p | f | 0 | -1 | 0 | |

When running it on a test database with 8.1.5 with replication
enabled it works fine there too.

Sorry about the noise,

Edwin
