Best possible way to increase the spead of the REINDEX It's hard to answer that without more information, like PostgreSQL version and configuration, for starters.

A good VACUUM policy should make such runs unnecessary in most cases -- at least on recent PostgreSQL versions. -Kevin -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
