Hi,
The thing is, although it shows 0.15 seconds, when I run the actual
query,
it takes around 40-45 seconds (sorry I forgot to mention that). And
then
sometimes it depends on data. Some parameters have very less number of
records, and others have lot more. I dont know how to read the
"explan"
results very well, but looked like there were no sequential scans
and it
only used indexes.
The planner will look at the data you used and it may decide to
switch the plan if it realizes your're quering a very frequent value.
Another thing that may be a factor is the network - when doing
explain analyze it doesn't have to transfer the dataset to the client.
