salut a tous
je suis nouveau dans le postegres, concernant la creation d'une nouvelle base de donnée


Nom: base1
Hote:localhost
Port TCP:5432,
Base maintenance:postegres
Nom utilisateur:user1
Mot de passe:*******

je reçois un message d'erreur
The server doesn't accept connections: the connection library reports
could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 5432? could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5432?
If you encounter this message, please check if the server you're trying to contact is actually running PostgreSQL on the given port. Test if you have network connectivity from your client to the server host using ping or equivalent tools. Is your network / VPN / SSH tunnel / firewall configured correctly?
For security reasons, PostgreSQL does not listen on all available IP addresses on the server machine initially. In order to access the server over the network, you need to enable listening on the address first.

ou dois je changer dans la Hote: et ne pas ecrire localhost
ou dans le port tcp: et ne pas ecrire 5432 et faire 0000

et merci
