I think on-disk bitmap indexes would only beat GIN indexes in a read-only database on low-cardinality columns. For example, if you had a purchase_log table and wanted to know all the "blue" and "large" items sold at a specific store, I can see on-disk bitmap indexes doing well there. If you added the product number, or needed read/write, I think GIN would win. I just don't think we have enough deployments who need what on-disk bitmap are best at. -- Bruce Momjian <br...@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + As you are, so once was I.
