privs drop after alter table

["Gauthier, Dave" <dave.gauthier@xxxxxxxxx>]

v8.3.4 on linux

 

After this..

alter table fred alter column wilma set default 'dino';

 

...it appeared that a user that had insert,delete,update privs lost them.

I regranded and things went back to normal.

 

Is it correct for those privs to be dropped in this case?  If so, why (just curious).

 

Thanks in Advance
