Обсуждение: Size of Large objects
Hello, I'm new in postgres. I searched the archives, but I don't find an answer. So can anybody tell me the explicit size, which a clob or a blob can have in postgres 8.0?

The terms clob or blob are not used in PostgreSQL; the limitation is the same on all column types. -- Peter Eisentraut http://developer.postgresql.org/~petere/

Also, you can just say "varchar" with no specific length limit, which is
then more or less equivalent to "text".
