User function canceling VACUUMDB utility

Hi,

We are facing the following problem in a PG 8.2 server when trying to vacuum
one of our databases:

vacuumdb: vacuuming database "reimer"
INFO: vacuuming "pg_catalog.pg_database"
INFO: "pg_database": found 0 removable, 6 nonremovable row versions in 1
pages
INFO: index "pg_database_datname_index" now contains 6 row versions in 2
pages
INFO: index "pg_database_oid_index" now contains 6 row versions in 2 pages
INFO: "pg_database": moved 0 row versions, truncated 1 to 1 pages
INFO: analyzing "pg_catalog.pg_database"
INFO: "pg_database": scanned 1 of 1 pages, containing 6 live rows and 0
dead rows; 6 rows in sample, 6 estimated total rows
vacuumdb: vacuuming of database "reimer" failed: ERROR: invalid type name
"TT_TIT.SEQCAN%TYPE"
[root(at)serverdb backup]#

I dumped the database and found the following function using the
"TT_TIT.SEQCAN%TYPE" type name.

CREATE FUNCTION fn_uq_tit_rec_seqcan(character, character, character,
character) RETURNS character
AS $_$
DECLARE
pFILREC ALIAS FOR $1 ;
pSEQREC ALIAS FOR $2 ;
pPARREC ALIAS FOR $3 ;
pSEQCAN ALIAS FOR $4 ;
output VARCHAR(1000);
SEQCAN TT_TIT.SEQCAN%TYPE;
begin
IF pSEQCAN IS NULL THEN
SEQCAN := ProximoCodigo('TT_TIT',pFILREC);
END IF;
output := pFILREC||pSEQREC||pPARREC||COALESCE(pSEQCAN,SEQCAN);
return (output);
end;
$_$
LANGUAGE plpgsql IMMUTABLE;
If I drop the function the vacuumdb runs fine but I'm wondering how a
funciton can cancel the vacuumdb utility.

I'm not a function specialist but is there anything we can try to make
vacuumdb run with this function created?

Thank you!
