Ok.

Hrm. Yeah, weird. I think I just forgot, because I learned in this
patch that you can't do two of those %s in the append function, and I
had fixed it in all the other dumps. *sigh*

The other thing I was concerned about was a bit of code duplication,
especially for the comment on opclass function.

Out of interest, I notice you didn't commit my inv_api.c change to
delete comments on LOBs - where did you put it instead?
