Hi, I have build an index. When, i execute the query, it gives the result by sequential scan, not by using my index. I have already run vacuum analyze to collect some statistics regarding table.
May be sequential scan is giving faster execution time than my indexing. But i want to know how much time it would take in my indexing. For that, i have set enable_seqscan=off in postgresql.conf. But it still going through sequential scan. Even i tried to set for a particular session, by "set enable_seqscan=off" on psql terminal. It again going by sequential scan. Does any one having an idea to force postgres to use index scan? Thanks Nick
