Version check is redundant, right?

I understand that it's probably difficult not to end up with two sets
of parentheses here, but can we avoid ending up with three sets?

Also, I wonder if pg_get_partkeydef() should omit "PARTITION BY" and
pg_dump can add that part back.  Then this could say:

Partition Key: RANGE ((a + b))

...which seems a good deal more natural than what you have now.
