How to make silently truncate for char type - Mailing list pgsql-general

I upgraded postgresql 7.1 to 7.2 and found that many
sql cannot execute because version 7.2 does not
silently truncate the string for char(n) type during
insert a new row.
e.g. insert t (field1) value ('abcdef');
     where field1 is char(5) but I insert the string
has 6 characters.

How can I solve the problem except downgrade the
Postgresql?

Looking forward to your reply!!!
