Well, my short answer would be "use 7.3" ;-)

If you don't like that answer, the next question is did you really mean
7.2, or 7.2.4?  (Any answer other than "it's 7.2.4" is the wrong one ---
there are bad bugs in earlier 7.2.* releases, and you should update
immediately.)

If it is 7.2.4, and you want to investigate the problem, then look for
the core file left by the crashed backend process.  It should be in
$PGDATA/base/YOURDBNUMBER/core.  (If you don't see any core files, you
probably need to restart the postmaster under "ulimit -c unlimited" to
allow core files to be produced in crashes.)  Once you have a core file,
do this:

    gdb /path/to/postgres /path/to/core
    gdb> bt
    gdb> quit

Send along the gdb output and other details of the problem to the
pgsql-bugs list, and we'll take a look ...
