This is exactly my situation. All updated hit non-indexed fields, with a lot of lookups on indexes What's interesting for me is that I might want to move away from some heavy INSERT/DELETE cases to simply marking records as deleted on the application side with this. The benefit being that I retain the archive of "processed" items without having to move them, but get the advantage of good throughput for the smaller set of items being "worked on". Will be interesting to see how the design pans out. - August ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
