I do not have uncommitted data per se, but when I change the datamodel,
this change involves several tables and triggers and might span more
than one database (only one of them being from Oracle), There are also
non-database subsystems that participate in the distributed
transaction. The problem occurs if e.g. the non-database transaction
must abort the transaction for one reason or the other.

Right. But thus time it is not a feature, but a limitation that is not
as i see it is not in any way based on some requirement for logical
consistency - more like the opposite if anything.
