.LRN 2.0 requires either PG 7.3 or PG 7.4 ...
We generally try to support two Postgres major releases with each of our releases, but no more. PG 7.3 has been out for many months or a year or something like that and is very stable and reliable. PG 7.4.1 will be released very shortly and should fix any "new release" problems folks saw with PG 7.4.0 (though my understanding is that PG 7.4.0 is very stable and reliable, too!)
