"""

Main purpose of this upgrade is to change the unique key on the
 | 
						|
pushers table again (it was missed when the v16 full schema was
 | 
						|
made) but this also changes the pushkey and data columns to text.
 | 
						|
When selecting a bytea column into a text column, postgres inserts
 | 
						|
the hex encoded data, and there's no portable way of getting the
 | 
						|
UTF-8 bytes, so we have to do it in Python.
