When I try this commands, some error messages aren't right:
[postgres@math pgsql]$ createdb test
CREATE DATABASE
[postgres@math pgsql]$ psql test

Now, as you can see, the error says it couldn't create the index. It says
nothing about the table not been created, but it doesn't apeare anywhere.
This happens when I put the redundant UNIQUE to the serial data type.
If someone is asking why I do this, it's because I program also for informix,
and the serial data type in informix doesn't have unique values.
Hope someone can change these error messages, because it took me some time to
find out what was wrong.
Saludos... :-)
