Ah, I was looking into only *.sql files in rdbms/admin directory, forgot
about the *.bsq's :)
catalog.sql had other flag bits defined, but not these two...
Thanks Wolfgang, Tanel.
Not sure if it helps, but wouldn't "bitand(i.flags, 256)" and "bitand(i.flags, 512)" be the same as 0x100 and 0x200 below
(from sql.bsq):
flags number not null, /* mutable flags: anything permanent should go into property */ /* unusable (dls) : 0x01 */ /* analyzed : 0x02 */
