For manual workaround just insert url as jdbc expected format.
jdbc:postgresql://example.com:1521/db

Example in sqlalchemy:
engine = create_engine(f'jdbcapi+pgjdbc://{uname}:{pwd}@{host}:{port}/{dbname}')

@henrykp If your "uname" or "pwd" contains special characters, use urllib quote like this:

from urllib.parse import quote
uname=quote("Amy#clusterid")
pwd=quote("secert@123")
