Fail to look up for `public.table1` in the COPY command

[hengfengli]

When we use pg_dump, we get the following command, e.g.,

COPY public.table1 (id, col1, col2, col3, col4, col5, col6, col7, col8, col9, col10) FROM stdin;

But currently, we get the error "ERROR: Table not found: public.table1".
