At least at the database level.

right now we have another database-level flag "no_reserve".
Thinking about for what table to set these flags or not
will be difficult to remember and understand. Setting this
at database level is much easier :-)

Of course this parameters are not for server-level, as Yaffil's
win32_disable_file_cache. At first we can add header page flag,
than if it will be needed, add DDL extention for CREATE/ALTER table
for example as many table config options in Oracle, as you wish.
