Ok, I've attached new versions of list.c and pg_list.h -- this is just a
*rough sketch* of the new List code -- it definitely won't compile, the
intent is just to concretely specify the new List design. Also, I've
only updated the important list functions: I stopped at nth().

Because (a) implementing a linked list is pretty trivial (b) the only
difficult part is getting the semantics / API right. I don't see how
std::list would help with (b),
This is a repost of my 29 Oct 2003 message, which didn't seem to make it all
the way in. It restores Tcl 8.0 compatibility, which was lost in my patch to
fix corrupt binary data transfer in pg_lo_read and pg_lo_write. Sorry, this
is against PostgreSQL-7.4beta5 which was the latest when I did this

Hmm. We could certainly do it like that, but does this actually fix the

now is very late here ( 04:17 AM ) so I wrote
the wrong code ( not checked ) but show the idea of
avoid if.
This saves an if during addition of a list item, at the cost of
greater expense during list

This does suggest that it might be worth making the struct layout be
int NodeTag;
int length;
foo *head;
foo *tail;
since this would avoid some padding overhead on a machine where pointers
are 8 bytes and need 8-byte alignment.
