pg_restore problem to load constraints with tables

Hi,

When a table is reloaded wit pg_restore, it is recreated without indexes or constraints. There are automatically skipped. Is there a reason for this?

g_restore -j 8 -v -d zof /shared/pgdump/aq/backup/dbtest/shtest --no-owner --role=test -t  mytable 2>&1 | tee -a dbest.log
