Subject: [pgadmin-support] Migration from MS Sql server using the plug-in

It doesnt import identity fields as serials, and thus is not usable for databases using auto_increment.

 

It is usable because when it has finished it is trivial to do something like:

 
SELECT max(serial_col) FROM tablename;
CREATE SEQUENCE serial_col_id START <result of previous query + 1>;
ALTER TABLE tablename ALTER COLUMN serial_col SET DEFAULT nextval('serial_col_id');
CREATE UNIQUE INDEX serial_col_idx ON tablename (serial_col);
Regards, Dave.
