I have run gfix -sql_dialect 3, then extrated metadata and i have created
the database from metadata without errors and warnings. Do that mean that i
can change the database dialect without pump the data??

Are you sure are stored as 4 byte?. I have one domain for PK of type
integer, and if i try to change the domain from integer to bigint, the
engine raises an error, but if i try to change one domain of type timestamp
to date or time, no error is raised.

Thank you
