Subject: determining maxsize for character varying
Date: Sat, 16 Jun 2007 11:53:10 +0200
Message-ID: <1181987590.4673b306d4baf@imp.free.fr> (raw)

Hello i would like to know if not determining a max size value for a character
varying's fields decrease the perfomance (perhaps size of stockage ? or
something else ?)

If not it is a good way to not specify a max size value ?
If it has an importance is it possible to have a general environnment variable
saying to postgres to automatically truncate fields which postgres have to
insert or update with a length superior at the max length.

Sorry for my bad english...

Lot of thanks
