Is a corefile dumped in the database directory when this happens?
If so, can you get a backtrace from it with gdb?

Hmm.  We have been seeing some reports recently of other odd behavior
with the Linux RPMs (see the "ordering RH6.1" thread on pgsql-hackers).
Would you take the time to compile 6.5.3 from source and see if you
still see the same behavior?

If you do this, please compile the backend with full debug+assert
support, which is to say
  (a) add --enable-cassert to the configure command;
  (b) do   make COPT=-g all  instead of just make all.
That should make the gdb backtrace a lot more informative, if
a coredump happens...
