Sequenties in pgSQL 7.3.x - Mailing list pgsql-sql

I am using postgresql 7.3.x. I am upgrating a database PostgreSQL.

The main problem is how to change field last value in sequencde which exists in database.

I created script to read this field and then I'm drop the table, do modification and i'm must change this value to another value.

But DBMS returns me message like that
