This is a revised patch originated by Junji TERAMOTO for HEAD. [BTree vacuum before page splitting] http://archives.postgresql.org/pgsql-patches/2006-01/msg00301.php
I think we can resurrect his idea because we will scan btree pages at-atime now; the missing-restarting-point problem went away. Have I missed something? Comments welcome. Regards, --- ITAGAKI Takahiro NTT Open Source Software Center
