Hello

Patch does not apply to master. Could you rebase?

Code looks good and very similar to "ALTER TABLE ... ALTER COLUMN ... DROP IDENTITY"

I noticed one bug:

create table testdrop (i int, b int, m int GENERATED ALWAYS AS ( i*2) stored);
insert into testdrop(i,b) values (3,4);
alter table testdrop alter COLUMN m drop expression ;
alter table testdrop drop column i;

Here is no "m" column anymore. Possible due some forgotten dependency?
