Not much, probably. We were going great guns before GB was formed because the PG developers were going great guns. This will probably slow the pace of 7.2 development - I was hoping GB would last until that version, with its replication and good backup facilities, was complete.
The MySQL crowd will probably crow over this, at least in part because they've been feeling bad that their world's been filled with bitter lawsuits recently. This will make them feel better :)
