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.
