There are at least > three good reasons for psql to be more forgiving of version mismatches > than pg_dump is: One more difference, pg_dump is backward compatible. i.e. you don't have to use the -i switch to run pg_dump v 8.1.x against pgsql v < 8.1 because pg_dump knows how to back up older version of the db on purpose. So, pg_dump is VERY forgiving going in one direction, as it should be, and very unforgiving going in the other, again, as it should be.
