That's not quite the right filter. You want to screen out everything that isn't a unique index, not just the primary key ones. You probably can't drop any of those without impacting database integrity.
Ah yes. I was considering adding the clause for unique indexes. Filthy constraint violations.
Also, as a picky point, you really should use functions like pg_relation_size instead of doing math on relpages.
You know, I always think about that, but I'm essentially lazy. :) I personally haven't ever had the old *8 trick fail, but from your perspective of working with so many variations, I could see how you'd want to avoid it.
I'll be good from now on. ;) -- Shaun Thomas OptionsHouse | 141 W.
