42  * Diagnosis of certain errors requires that either a) the type of ereport be
43  * recorded in a persistent buffer or b) that a single value be used to
44  * represent multiple ereport classes.  We start the values at 0x8 to avoid
45  * collisions with an earlier class code enum.  While we have 64 bits available
46  * to us, cmd_errcl_t's are saved in persistent buffers, and thus can't easily
47  * grow beyond that size.  As such, ereports should only be assigned class codes
48  * when needed.  NEVER CHANGE the values of these constants once assigned.
