Boy, that backtrace certainly looks exactly like the hashjoin problem
that I thought I fixed ... and Rae Stiening, the original complainant,
confirmed that the patch fixed the problem for him.  You're certain
this is 7.3.2?

I'd recommend rebuilding with --enable-debug so you can get a more
detailed stack trace.  The thing I'd want to look at is whether
ExecHashJoinGetBatch() is returning an out-of-range batch number to
ExecHashJoin() just before the crash occurs.  It would also be useful
to look at the nbatch, nbuckets, and totalbuckets fields of the
hashtable structure in ExecHashJoin.
