Hi,

Unfortunately, patch doesn't compile anymore due:

varlena.c: In function ‘text_position_next_internal’:
varlena.c:1337:13: error: ‘start_ptr’ undeclared (first use in this function)
  Assert(start_ptr >= haystack && start_ptr <= haystack_end);

Could you please send an updated version? For now I'm moving it to the next CF.
