Hi
I am trying to add a query progress indicator in postgres.Being a
novice to the code I need help on few topics.
1.Where can we keep such a progress indicator code ?
2.What is the exact structure of plan returned by the planner ?
3.Does the planner return the estimates calculated while deciding the
plan ?
4.If not , then from where can we obtain those estimates ( estimates
taken to decide the best plan ) ?
I will be very thankful if someone can throw light in these
issues and provide some related guidance
regards
Anuj

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
