[typo] Postgres Issue with Migrate BoolifyContentAllowFoo

[Paul Hart]

Jeffrey, Piers,

Thanks for your help so far. I'm on the digest version of the mailing 
list, so I'll respond to both of you in turn.

Piers: I might roll back to 739, but I'd prefer to have this fixed (and 
do what I can, if anything, to help). I haven't been on IRC in years, so 
I guess the person you were chatting with wasn't me! :)

Jeffrey, I modified the code as you suggested in your mail. That fixed 
the issue with the allow_comments, but now it's hanging up on 
allow_pings. I find that weird, because it appears (to my 
rails-newbie-ish eyes) that the migrate script should be doing both 
allow_comments and allow_pings.

I'm guessing that by doing the two separately postgres is happy about 
the one fix, but whiney about the second not being there yet? My rails 
UPDATE statment always seems to include all the columns regardless of 
which ones have changed, and that would be an issue given this method of 
solution.

In a way it's halfway there; in another it isn't really ;)

Paul
