I do that all the time. I normally am running under an emacs terminal so I don't know what width the ioctl's going to get back but it's unlikely to be right. In any case I may want to format the output to a width narrower than the window because I'm going to narrow it. Also, how would you suggest figuring the width to use for output going to a file? ioctl is irrelevant in that case, imho it should just default to 80 columns if COLUMNS is unset. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com Ask me about EnterpriseDB's Slony Replication support! -- Sent via pgsql-patches mailing list (pgsql-patches@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-patches
