I added some debug support, and there are only two classes called UUID when
this fails:
uuid UUID: <module 'uuid' from '/usr/local/lib/python3.6/uuid.py'>
psycopg2.extensions UUID: <module 'psycopg2.extensions' from
'.../python3.6/site-packages/psycopg2/extensions.py'>
The psycopg extension is a converter, and it seems highly unlikely that it
was put into place as the value, and I doubt it would report it's __str__
as the UUID string, so it does not appear to be a case of mistaken
identity. Which makes the failure of "not instance" to catch the UUID after
a while all the more weird...
I'm pretty baffled on this one. Am I really the only one running into this?
