Postgres is not able to cluster a relation on which an rtree index is
defined. Postmaster gives the following error message:
Too Large Allocation Request("!(0 < (size) && (size) <= (0xfffffff)):size=0
[0x0]", File:"/export/home/postgres/src/backend/utils/mmgr/mcxt.c", Line: 220)
!(0 <(size) && (size) <= (0xfffffff)) (0) [No such file or directory]
