The intended use of pg_isready is to find out if the server is alive, not whether any particular user or database name is correct. So it treats responses like "no such database" as sufficient proof that the server is alive. As David says, you could try to log in with any other client software, or connect using known-good parameters and check the system catalogs. regards, tom lane
