We can use syntax like: "alter publication pub1 set table t1 where (c2
> 10);" to reset the existing row filter. It seems similar thing works
for column list as well ("alter publication pub1 set table t1 (c2)
where (c2 > 10)"). If I am not missing anything, I don't think we need
additional Alter Table syntax.
