of this x>=4 master segfault (expecting a zero when there is
none). Remaining compatibility problems are: the older slave will not
find the catalog; but it is will not crash, and it's not an issue
that it does not find the catalog as catalogs were not used in these older
MySQL versions (we store it in binlog and read it from relay log but do
nothing useful with it). What is an issue is that the older slave will
stop processing the Q_* blocks (and jumps to the db/query) as soon as it
sees unknown Q_CATALOG_NZ_CODE; so it will not be able to read
that it does not find the catalog as catalogs were not used in these
older MySQL versions (we store it in binlog and read it from relay log
but do nothing useful with it). What is an issue is that the older slave
will stop processing the Q_* blocks (and jumps to the db/query) as soon
as it sees unknown Q_CATALOG_NZ_CODE; so it will not be able to read
Q_AUTO_INCREMENT*, Q_CHARSET and so replication will fail silently in
various ways. Documented that you should not mix alpha/beta versions if
they are not exactly the same version, with example of 5.0.3->5.0.2 and
5.0.4->5.0.3. If replication is from older to new, the new will
recognize Q_CATALOG_CODE and have no problem.
