[firebird-support] FB3 and not null

[liviuslivius liviusliv...@poczta.onet.pl [firebird-support]]

Hi,
 
in earlier versions of Firebird - when i try to change column nullable to not 
null
this go very very fast but without check of all records contain value in such 
field.
I see that in FB3 this was changed and before apply not null to column - all 
existed data are validated.
 
Is three some possibility to disable this behavior?
On my big table with 910 468 710 records this operation take 72 minutes.
I am sure that all records contain value in this field and this check is then 
"useless".
 
regards,
