Thank you very much ! To everybody who have replied, and especially to Roman.

We are fixing now DbSchema for Firebird.
In case you have interests for DbSchema, I can send you a license key, just let me know.

should return if schemas are not supported, but I believe the default
reaction specified is to return an empty resultset (at least that is
