Oh yes, I discovered that it should be set inside
GDS_Impl.isc_attach_database(). But obviously it is not.

I cannot trace what data runs inside methods because in fact I am
using ryanb's embedded version of Jaybird and I don't know where (or
if) sources for it are available.
It would be nice to be able to look inside them...
