Why does this not work:
postgres=# ALTER TABLE tab1 ALTER COLUMN nr TYPE serial;
ERROR: type "serial" does not exist
serial is really just "short-hand" for making an integer column use
default incrementing function. The following will fully explain what
it is so that you can alter the column:

Thanks Richard, that helped. I thought maybe there is another reason
because when I create a table and use serial as "type" (like I would
when I use integer) it works well. I know that searial is just for my
convenience as written in the manual. I failed to understand, that it is
not really a type.
