you have to check your PostgreSQL setup to enable access for the agent. Please confirm that you are using IPv4 for connection. It might be that you are using a domain socket or IPv6 instead, so your setting won't work. Check postgres logs for further details. So either configure access without password prompt or provide a password.

Tell me where to put the .pgpass file for alternative authorization. And also tell me the output key the size of the base
