The package uses absolute imports for importing the C extension, e.g.

from psycopg2._psycopg import __version__

This cannot work in Python with frozen packages. Not in Python 2 and
not in Python 3 either.

Christian: Your only option is not to freeze the psycopg2 package
and ship it along side your frozen application or to build the
frozen app with the psycopg2 C extension built statically.

In any case, freeze is not at fault here.
