Is that related to the new hex-escaping format in postgres 9?

My memories about this have faded, but IIRC we came to a stage where it 
might _seem_ to work, but with raw binary data being passed off as text. 
  Might not have caught the problem without some very specific tests.

I believe there was also the complication that when you write your own 
column type in django, your custom conversion functions can receive 
values that need converting, or values that have already been converted. 
  They won't know which.  But I guess there's ways around that.
