The Query plan did change a little bit but the performance was not impacted. CREATE INDEX idx_arcstatus_le1 ON schema.logtable ( archivestatus ) where (archivestatus <= 1) ANALYZE schema.logtable This resulted in this query plan: [...] I assume (4000,4001,4002) are just example-values and that they might be anything? Else you can just include them in your partial-index. -- Andreas Joseph Krogh
