wangyan 22411cf6b2 Fix pgsql creation column bug ... Root cause: Use default 'now'::timestamp will not generate timestamp for each transaction, PG will convert now to a timestamp as soon as the constant is parsed. To fix it, update it to defult CURRENT_TIMESTAMP, thie setting is the same as default now(), which returns the start time of current transaction because ther are fuction calls, hey will give the desired behavior of defaulting to the time of row insertion.
