sigo recibiendo errores al intentar conectarme a postgres desde google colab, sin embargo, en pycharm, este mismo código se conecta fácilmente al servidor. Aquí está el código:

 import psycopg2 params = { "host" : "localhost", "database" : "somedb", "user" : "postgres", "password" : "mypassword" } def connect(params): """ Connect to the PostgreSQL database server """ conn = None try: # connect to the PostgreSQL server print('Connecting to the PostgreSQL database...') conn = psycopg2.connect(**params) except (Exception, psycopg2.DatabaseError) as error: print(error) return conn connect(params)

errores que estoy recibiendo

 OperationalError: could not connect to server: Connection refused Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5432? could not connect to server: Cannot assign requested address Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 5432?
