That shouldn't happen :-(. Look for a core file in $PGDATA/base/yourdb/core
(if you don't find one, you probably need to restart the postmaster with
"ulimit -c unlimited" to allow core dumps). Then do
gdb /path/to/postgres/executable /path/to/corefile
gdb> bt
gdb> quit
and send us the results.
BTW, what Postgres version is this, and what are the declarations of the
tables being loaded?
