If you want to figure out how psql is figuring this out, you can pass it -E when you connect. Why do you care though? CLUSTERing is a rather limited fix for a rather specialized type of problem, it's not something that's worth setting for every table and almost certainly not just blindly doing it on the table's primary key. -- Sam http://samason.me.uk/ -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
