This PR is to improve the exception message I faced when running Tortoise.init with the option _create_db=True. This creates a connection without database set. But asyncpg library internally try to set database as os.getenv('PGDATABASE') or as the db username otherwise. This issue happened to me when running with WSL + docker; the exception error message gave me no clue what was happening. So, after a lot of debugging, all I had to do was to set 'PGDATABASE' environment as 'postgres'.
