Re: alter table drop column status

That's the only way to do it at the moment - would you like to collaborate
on the actual sql script to get this done?  I wonder if it could be done
entirely with a stored procedure?  That'd be cool:

select drop_column(mytable, mycolumn);

Sweet :)

I'd like to implement this for phpPgAdmin as well.
