Problem with too short column

Hi,

I actually try to insert varchar which length is higher than 32 in a column
which type is varchar(32). I can't change the type of the column, and I
want to trunc the data. I know it's possible ! I have seen this !

Example : "j'aime les saucisses avec du beurre dedans" will be "j'aime les
saucisses avec du beu". For the moment it produces a SQL Error !

Is it an option in the config files ?

I'm using Postgresql 7.2.2.

Thanks in advance.
