Dear Posterity,

For the unfortunates with similar problems who find this message with google 
or something similar down the road:

This silly problem is a result of SQL keywords being capitalized.  Change 
'FROM' to 'from' and 'AS' to 'as' (I kept the USING UNIQUE and USING SRID as 
capitals and I'm leaving it that way since it's working) and put one foot on 
a north-facing wall while smiling through half your mouth (it doesn't seem to 
matter which side) and the problem goes away.

Regards,

Fred
