    Upgrade mypy to 0.942 to fix support of types-psycopg2 >= 2.9.12
    
    types-psycopg2 2.9.12 contains this commit:
    https://github.com/python/typeshed/commit/506be4fb0adcf38af77325258af337772abcde77
    
    which removes `Any` as the return type of the last variant, allowing
    mypy to type-check the returned value.
    However, mypy 0.920 only considers the last variant, even though we use
    the first one; causing the return type to be badly inferred, and
    erroring every time we use it as context manager.
