Yeah, let's move on here, but not with this patch I am afraid as this
breaks any client utility using xlogreader.c in frontend, like
pg_xlogdump or pg_rewind because MemoryContextAllocExtended is not
available in frontend, only in backend. We are going to need something
like palloc_noerror, defined on both backend (mcxt.c) and frontend
(fe_memutils.c) side.
Btw, the huge flag should be used as well as palloc only allows
allocation up to 1GB, and this is incompatible with ~9.4 where malloc
is used.
