I was just speculating about possible future problems.  Given the code
I committed last night, a 7.0 pg_dump will refuse to run with a 7.1
database (or vice versa, unless we change the version-checking code
before 7.1 is released).  Now maybe that combination would have worked
anyway --- but we don't know yet.

I did put in a switch to override the version check, so if you know it
will work you can use that switch.
