I'm trying to work through a root cause on a performance problem. I'd like to be able to "show" that a problem was fixed by analyzing the table. what i've done is set default_statistics_target=1 analyze <Table> That gets rid of most of the rows in pg_stats, but i'm still getting decent performance. It's possible that the existing stats were just not optimal, and i won't be able to get that back. But I just want to verify that what i've done is the only real option that I have? am i missing anything else that I could try? (I'm on PG9.1) Thanks.
