not sure if you're wrong. but at the very least, you miss a
heap_freetuple(oldtup) there, because get_catalog_object_by_oid()

no, that code is not unchanged because function
get_ext_ver_list_from_catalog() comes from your patch.
it's seems the thing is that function get_ext_ver_info() is append a
new ExtensionVersionInfo which is then returned and assigned to an
*evi pointer that is never used.

i'm sure that evi in line 1150 is only because you need to receive the
returned value. Maybe you could use "(void) get_ext_ver_info()" (or it
should be (void *)?) to avoid that assignment and keep compiler quiet

PS: i'm on gcc (Debian 4.7.2-5) 4.7.2
