Hi,
Thanks for your reply, but I have some doubts.
Are yoy sugesting I create the column as an Integer then change it to
Serial? in Pgsql 7 you cant change a column type.
If I create the column as an int then add a default value, how can I make
this default value increment with each insert?
Thanks again for your help.
Marcelo
