Обсуждение: psql ERROR : Character Types Tuple is too big: size xxxxx
Hi, From Bruce online book : "There are synonyms for the terms table, row, and column. Table is more formally referred to as a relation or class, row as record or tuple, and column as field or attribute. " ==== 8Kb limit apply to : 'tuple' when insert ? 'tuple' in design stage (what's append with fixe types) ? column (Case of fixe types) ??? What's wrong ? - Design database - Postgresql limit Can't find informations on documentation and mail archive's obscure on 8Kb limit. Thanks fo help.

Well, you've got six fixed-size 2K fields, which are going to take up
12K all by themselves, plus there's a few dozen bytes of overhead.
I'd suggest using varchar or text instead of char --- do you really
need 12K of blank-padding in every record?

and on top of that, why insert character strings into columns expecting
numeric values?
defintely use VARCHAR unless you are going to be filling those columns up
