The problem is that when it is trying to load the revised functions from
the above file, something is breaking.

1)  Verify that the file named actually exists; if it doesn't, then
there's some mispointing to the wrong slonik, more than likely...

2)  Take a look at PG logs to see what function revision is failing.  I
did do test runs against 7.3.9, but not specifically of UPDATE FUNCTIONS. 
It's plausible that maybe some function has changed signatures, and
there's some complaint about that.

Dropping (out of band) an existing stored function might do the trick...
