My Table Columns (all bigints): start, stop, step1, step2, step3

^^^^^^^^^^^



The Query: explain analyze select * from path where start = 653873 or start = 649967 or stop = 653873 or stop = 649967


Does anyone have a suggestion on how to get that query to use an index?


Coerce the constants to bigint, for starters.  However, a query that is
selecting almost 10% of the table, as your example is, probably
*shouldn't* be using an index.

I think that for 10% is still better and Index scan. There is around a way to calculate this elbow ?
