For example, it wouldn't handle multi-byte characters properly. And it wouldn't handle integers properly either - you'd end up sorting negatives after positives. You could possibly still find applications for it but they'd be quite narrow, I think. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise Postgres Company -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
