Comment (by pramsey):

 This is such a large collection of functions, it would stand to reason
 that a simpler version would still crash, but this doesn't, even though I
 think it's pushing the same stuff into the buffer call.
 {{{
 select st_buffer(st_collect(tab.shape::geometry)::geography, 10) from tab;
