This is exactly the reason why in db2 _no_ guarantees are made
regarding the constancy of the system catalogs (that are in the SYSIBM
schema). Instead, the equivalent views (in the SYSCAT schema) are
_never_ broken (whether in a point release or a new version). In fact,
the SYSCAT views correspond to the ISO SQL standard.
