After removing the explicit reference to the 'public' schema from the
code, the 'migrate' command works correctly with the non-public schema.

Maybe there is no need to explicitly set the schemas in the
configuration file?

I think that if the 'initialise' command is supposed to check for the
presence of the database and schema first, then it shouldn't only get
the values from the configuration file. It would be better to take them
directly from psycopg if possible.
