FWIW you could use an slist from ilist.c. It means each node would need a "next" pointer, but there's no separately allocated list cell. There are many places that could use slist/dlist. For instance while reading the SET PERSISTENT patch I noticed it has head and tail pointers being passed all over the place, which looks rather ugly. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
