hi If you are still not able to make column as AUTO_INCREMENT while creating table. As a work around first create table that is:

create table student( sid integer NOT NULL sname varchar(30), PRIMARY KEY (sid) );

alter table student alter column sid set GENERATED BY DEFAULT AS IDENTITY

alter table student alter column sid set GENERATED BY DEFAULT AS IDENTITY (start with 100)
