Hi Michael,
I can't see too much from this query plan, it just seems you have 321
triggers an 4750 dependencies which isn't too extraordinary much. But 48
seconds execution time *is* much.
Please repost this to pgsql-performance, including the query, backend
version, and modified server settings. I'm not deep enough in planner
items to analyze this sufficiently.
Please let me CCd on this topic so I can see what I should change in
pgAdmin3 (if any).
Regards,
Andreas
