Hi,
I want to see more query plans, other than the default one for a query
and compare their cost. Based on this, I can change the cost model and
see how that can affect the cost model?
I enabled the debug information in postgresql.conf. But it looks like
the output is still for the best plan only. Is there any way to see
them, before I go to the code and implement sth myself?
Thanks very much.
