Hi
How would you optimize a query with greater than in where clause eg
select * from table1 where id > 1000
and there is an index on id column
The question as written is unanswerable.
- Why do you think it needs to be optimized?
- What is the table cardinality, and the query cardinality?
- What does EXPLAIN say?
- Have you run ANALYZE on table1?
Bottom line: Postgres might think that it is more efficient to scan the whole table.
