Postgresql on vscode

When I try to create connection profile I keep getting those two errors:

PostgreSQL: Failed to connect: 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?

and
PostgreSQL: Error: Unable to connect using the connection information provided. Retry profile creation?

I have tried fixing for ages but nothing changed.
