One thing I love about PostgreSQL development is all the small nice fixes added in every version. Of the small fixes in 9.1 my personal favorite is probably the cleanup of pg_stat_activity. There are also many other nice small fixes like improved tab completion for some commands and the ability to set environment variables in psql.
