I'm not as familiar with later versions of MS-SQL, but it's replication story is well in the box... Postgres is a bolted on, hard to setup/maintain hodge podge... I really hope the out of the box, via a gui admin and all story for replication on postgres gets to where MS-SQL was in the box in 2005.

NOTE: this is not a bash or nag on postgres, I really like it's JSON integration, and plv8 is awesome. That said, even simple replication stories in pgsql have me pulling my hair out, mainly because I don't WANT to know every intricate detail about my dbms, I just want to build applications on top of it, and ms-sql is pretty nice in that regard.
