Let me know if this is correct.  I made this change to the init script:

[root@bilbo ~]# diff /etc/init.d/postgresql /etc/init.d/postgresql_strace
190c190
<       $SU -l postgres -c "$PGENGINE/postmaster -p '$PGPORT' -D
'$PGDATA' ${PGOPTS} &" >> "$PGLOG" 2>&1 < /dev/null
---
 >       $SU -l postgres -c "/usr/bin/strace $PGENGINE/postmaster -p
'$PGPORT' -D '$PGDATA' ${PGOPTS} &" >> "$PGLOG" 2>&1 < /dev/null

...which gives this output to the log file after running "service
postgresql start":
