pg_dump: schema with OID xxxxxxxx does not exist

Running pg_dump gives this error:
pg_dump: schema with OID 37647910 does not exist

I've found a variation of this on the mailing list, but I'm not entirely
sure what to do about it.

I found this OID by running: select * from pg_type where typnamespace =
37647910;

and two entries:

typname | typnamespace | typowner | typlen | typbyval |
typtype | typisdefined | typdelim | typrelid | typelem | typinput |
typoutput | typreceive | typsend | typalign | typstorage |
typnotnull | typbasetype | typtypmod | typndims | typdefaultbin | typdefault

record_out | record_recv | record_send | i | p |
f | 0 | -1 | 0 | |
(2 rows)

Does this mean that I can just delete these rows from this table for the
dump to work? Will deleting these rows affect anything else? Can you
tell that I'm not really sure what I am doing - I just need to get a
database from one server to another.

Thanks for any help you could give me,

Peter
