Not a bug; and likely to simple to have escaped notice this long so the
first reaction should be "what am I missing here?"

[google: round .5 postgresql]

http://grokbase.com/t/postgresql/pgsql-hackers/03ap11tckn/round-function-wrong/oldest

Round( numeric ) - 0.5 rounds away from zero
Round( float ) - platform dependent, IEEE 0.5 rounds toward even

You can argue the decision but at this point it's not likely to change.
