Hi, I have learnt from certain texts that bitmap indexes are very useful for large DSS (decesion support systems).
bitmap indexes are currently not available in postgresql. My question is in what way is a normal btree index in pgsql inferior to bitmap indexes (found in oracle for example). is it just in terms of space requirements for performance too? regds mallah. -- Rajesh Kumar Mallah, Project Manager (Development) Infocom Network Limited, New Delhi phone: +91(11)6152172 (221) (L) ,9811255597 (M) Visit http://www.trade-india.com , India's Leading B2B eMarketplace. ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
