pg_dump incorrect sequence value

Hi,

I had dumped data using the command:

pg_dump -U dbowner dbname -a -t table -f table-data.sql

two tables (e.g. table1, table2).

In the first table - the correct sequence was set as can
be seen at the end of the dump file:

....
SELECT pg_catalog.setval ('table1_id_seq', 20, true);

but in the second table - the sequence was incorrect:

...
SELECT pg_catalog.setval ('table2_id_seq', 1, true);

Question:
How do I correct this so that dumping data sets the
correct sequence value?
