In the docs at http://www.postgresql.org/docs/9.0/static/sql-createindex.html, I see that you can build indexes that include ordering. Eg. create index t_col_idx on t (col DESC NULLS LAST); Does that mean that the initial creation of the index acts like the CLUSTER command? If so, what happens to subsequent inserts/updates of the indexed attribute? Are those values then indexed in the order that they are inserted -- which could be contrary to the ordering specified in the index creation? -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
