[GENERAL] pg_restore successful with warnings returns exit code of non-zero

" /usr/bin/pg_restore -a -v -d db1 -F c " and the input is passed in from stdin. It warns on a couple of existing rows, but completes successfully with "WARNING: errors ignored on restore: 5".

However, this returns a exit code of 1 eventhough the command is run fine and data is restored. Is there a way to tell pg_restore to return 0 in this case ?

Thanks
