Once a day I would like to reindex my database (and maybe re cluster it - don't know if that's worth it yet?). I need the database to be usable while doing this (both read and write). I see that there is no way to REINDEX CONCURRENTLY - So what approach would you suggest that I take on this? If you have the diskspaec, it's generally a good idea to do a CREATE INDEX CONCURRENTLY, and then rename the new one into place (typically in a transaction). (If your app, documentation or dba doesn't mind the index changing names, you don't need to rename of course, you can just drop the old one). -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
