We just came upon a crash bug in Postgres >= 8.2. The attached

reproduces the crash for me on 32-bit machines (i686) but NOT on 64 bit
machines (x86_64), for Postgres 8.2 and cvs-head, but not on 8.1. We've
verified this on about four 32 bit machines, and four 64 bit machines
(including one each under vmware on the same host). All machines were
some flavor of Red Hat, Fedora, or Gentoo.


Hmm. There seems to be something wrong in the free space calculation in the algorithm for choosing the right split location. I'll dig deeper, unless someone beats me to it..
