Description:
I am reading 14.1.1 and at the very end (just before 14.1.2) I see:
"which shows that the planner thinks that sorting onek by index-scanning is
about 12% more expensive than sequential-scan-and-sort."
I feel that 12% is incorrect, but I'm not quite sure. The costs are 268.19
and 292.65, and that's about 9% more expensive?
I'm not entirely sure though; just reading up on explain plans :)
With kind regards,
Jurrie
