Thanks. The side effect is that it would suppress other notices which might 
be useful.

I was looking for a way to suppress the notice within the CREATE TABLE 
statement but could not.
I noticed that when I specify a constraint name for the primary key, it 
would create an implicit index with the constraint name. So may be if the 
optional constraint name is specified by the user, then the notice can be 
suppressed. Indeed the manual already says that the index will be 
automatically created.

BTW, there's an extra space in link[2] above which I have removed.

Best regards,
KC.
