The big hit comes with command_string. However, row level stats bring a big enough penalty (~10% on my usage) that I keep them turned off. The penalty is not just run time either, but increased cpu time. It just isn't an essential feature so unless it causes near zero extra load it will stay off on my servers. Additionally, back when I was testing the win32/pg platform I was getting random restarts of the stats collector when the server was under high load and row_level stats were on. This was a while back so this issue may or may not be resolved...it was really nasty because it cleared out pg_stats_activity which in turn ruined my admin tools. I should probably give that another look. Merlin
