Note that you can use the CONCURRENTLY option to create index, and it will not require a lock on the table, so you can doit while the db is being used. It takes longer, sometimes a lot longer, than the regular create, but who cares? Start itand leave it. After you’ve done that and seen how much benefit you get just from indexing your most-commonly used column, post a rangeof common queries back here for further advice. -- Scott Ribe scott_ribe@elevated-dev.com http://www.elevated-dev.com/ https://www.linkedin.com/in/scottribe/ (303) 722-0567 voice
