pg_dumpall failed

Hi, all,

I am using  pg_dumpall (pg_dumpall -o > backup) to backup postgresql
7.2.3 datatbase on Redhat Linux 8. It worked well, but recently, it
failed and gave me the following messages:

pg_dump: query to get data of sequence "est_att_p_por_id_seq" returned
name "est_att_p_porites_id_seq"
pg_dumap failed on xxxxx, exiting

Can anybody tell me what might go wrong here?

Thank you very much for your kind reply.
