Well, oldtup can be either a syscache copy or a heap tuple. I've been
looking at other call sites and they don't free their tuple either. So
I'm leaving it at that for now.

Yes. Here's the relevant hunk:

***************
*** 997,1003 **** get_nearest_unprocessed_vertex(List *evi_list)
* the versions that can be reached in one step from that version.
*/
static List *
! get_ext_ver_list(ExtensionControlFile *control)
{
List *evi_list = NIL;
int extnamelen = strlen(control->name);
--- 1093,1099 ----
* the versions that can be reached in one step from that version.
*/
static List *
! get_ext_ver_list_from_files(ExtensionControl *control)
{
List *evi_list = NIL;
int extnamelen = strlen(control->name);
***************

So the content of the function has not changed. I'm not opposed to
trying to fix it, I just don't think it would be wise to do so as part
of the extension templates patch, as I do believe that the problem
should manifest itself in head too: it's the same code under a new
function's name.
