I've not thought about another parameters...

Since I could avoid unexpected setting(round-down to zero) with rounding it up. And document this on "18.1.1. Parameter Names and Values". regards, ---------------- Tomonari Katsumata -- Sent via pgsql-docs mailing list (pgsql-docs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-docs
