Hi,

When I set engine as below,

engine = 
sa.create_engine('redshift+psycopg2://usern...@xxx-edm-oregon-prod02.cgdmyxu24bfx.us-west-2.redshift.amazonaws.com:5439/bdpdw?tcpKeepAlive=true&ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory')

it's no error. But when I try to 

print(engine.table_names())

it gave me this error 

ProgrammingError: (psycopg2.ProgrammingError) invalid dsn: invalid connection 
option "tcpKeepAlive"
 (Background on this error at: http://sqlalche.me/e/f405)


and then I try this way


engine = 
sa.create_engine('redshift+psycopg2://usern...@xxx-edm-oregon-prod02.cgdmyxu24bfx.us-west-2.redshift.amazonaws.com:5439/bdpdw')


then print(engine.table_names())


it gave me this error message

OperationalError: (psycopg2.OperationalError) fe_sendauth: no password supplied
 (Background on this error at: http://sqlalche.me/e/e3q8)


Not sure, how should i do?
