[pgpool-hackers: 3597] Do we want to change successfull authentication log priority?

[Tatsuo Ishii]

Recently we have multiple complains from users about successfull
authentication log.

Currently each time when Pgpool-II succeeds with client
authentication, following log is out:

pool_auth.c-				{
pool_auth.c:					ereport(LOG,
pool_auth.c-							(errmsg("using clear text authentication with frontend"),
--
pool_auth.c-			{
pool_auth.c:				ereport(LOG,
pool_auth.c-						(errmsg("using clear text authentication with frontend"),
--
pool_auth.c-	}
pool_auth.c:	ereport(LOG,
pool_auth.c-			(errmsg("clear text authentication successful with frontend")));
--
pool_auth.c-			frontend->frontend_authenticated = true;
pool_auth.c:			ereport(LOG,
pool_auth.c-					(errmsg("SSL certificate authentication for user \"%s\" with Pgpool-II is successful", frontend->username)));
--
pool_auth.c-			frontend->frontend_authenticated = false;
pool_auth.c:			ereport(LOG,
pool_auth.c-					(errmsg("SSL certificate authentication for user \"%s\" failed", frontend->username)));
--
pool_auth.c-	}
pool_auth.c:	ereport(LOG,
pool_auth.c-			(errmsg("md5 authentication successful with frontend")));

These flood out Pgpool-II log. I think they are too verbose and should
be downgraded to DEBUG1. Any objection?

Best regards,
