Hey Sxooter - what new stuff in PostgreSQL 8.1 are you looking forward to?
Moving pg_autovacuum into main sounds pretty significant. I guess I can remove my cron vacuums?
The replacing of users and groups with roles sounds pretty significant too - wonder if I'll have to worry about that.
The csv header option is a nice small touch.
Looks like there's some new IN/INOUT functionality for plpgsql that may replace RETURN.
Other than that, it appears there are also quite a few performance improvements.
