Too many messages from Autovacuum

Recommending downgrade of these annoying messages from LOG to DEBUG1:

2006-09-23 15:57:56 EDT_3147 LOG:  transaction ID wrap limit is 2147484170, limited by database "postgres"
2006-09-23 15:57:57 EDT_3147 LOG:  transaction ID wrap limit is 2147484170, limited by database "postgres"
2006-09-23 15:59:59 EDT_3394 LOG:  transaction ID wrap limit is 2147484170, limited by database "postgres"
2006-09-23 15:59:59 EDT_3394 LOG:  transaction ID wrap limit is 2147484170, limited by database "postgres"
2006-09-23 16:02:04 EDT_3646 LOG:  transaction ID wrap limit is 2147484170, limited by database "postgres"
2006-09-23 16:04:07 EDT_3892 LOG:  transaction ID wrap limit is 2147484170, limited by database "postgres"
2006-09-23 16:04:08 EDT_3892 LOG:  transaction ID wrap limit is 2147484170, limited by database "postgres"
2006-09-23 16:06:11 EDT_4138 LOG:  transaction ID wrap limit is 2147484170, limited by database "postgres"

No server settings seem appropriate to remove these...

So, patch enclosed to change LOG -> DEBUG1

Other suggestions welcome...
