I am satisfied with functional indexes - it works in my pg 7.4.x.

On more investigation I found that index scan is not used if the query have a function in it like lower() and an index exist for lower() column.

Hi all, I am facing a strange problem when I run EXPLAIN against a table having more than 100000 records. The query have lot of OR conditions and when parts of the query is removed it is using index. To analyse it I created a table with a single column, inserted 100000 records(random number) in it created index and run a query which returns 1 record which have no or condition and it was using index. I added an OR conditon and is using sequential scan. I set the enable_seqscan to off. I ran the tests again and is using index scan. So which one I have to use. Is this any bug in Explain.
