I have thought on that possibility since the start and the conflict points I see are: - Name of RDB$PROFILE_STATS - perhaps RDB$PROFILE_PSQL? - New parameter(s) in START_SESSION specifying profile options - when there are possible options I see a need each time a system package is created to have: - Named parameters (kind of Oracle =>), perhaps with := - Default parameters Both things are very nice thing to have but the way it is, does not break extensions (new parameters with DEFAULT added). I do not mean it should (or should not) be integrated before RecordSource profile, but that the design is not very impacted.
