Oops, that's not too much. In the docs I've seen a 4-byte length
descriptor, thus expected a size limit of 4 GB and felt quit safe
with a maximum size of 300 MB.

Yes, storing large data objects in the file system is advisable for
several reasons - we've had the same discussion times ago with mysql as
well. But the decision was made to keep it in the database (and there is
only one object of this size anyways). Rewriting the framework is not an
option at the moment.
If I fail to migrate this into postgresql, we'd rather cancel the
transition.
