Error accessing the table from an app with label changed

[psnma]

I created an app and using AppConfig I changed the label to another name ('abc' to 'my_abc'). The migration was successful and the table was created with the label prefix (table 'my_abc'). But when I access the page, Django emits an error that is trying to access the table without taking into account that has changed the name of the label, it is trying to access the table "abc", but should access "my_abc".

ProgrammingError
relation "abc" does not exist

I can't reproduce this. I created an AppConfig for the poll app in the tutorial and change its label. When I set label = 'foo', I get no such table: foo_poll when trying to access the admin change view.

My problem was because of the '.pyc' files. Is working properly.
